△^9-Tetrahydrocannabinol (△^9-THC), cannabinol, cannabidiol and cannabichromene were detected in commercially available cannabis seeds by silica gel TLC and gas chromatography. These cannabinoids existed in rather high content (0.10-2.02mg/100g of seeds) in the feed for birds, especially bracts (82.3-441mg/100g). When the suspension prepared from the benzene washing solution of cannabis seeds, BenW, was administered at a dose of 3mg/kg corresponding to △^9-THC into a mouse, i.v., BenW caused hypothermia, catalepsy, pentobarbital-induced sleep prolongation and suppression of locomotor activity. These pharmacological activities of BenW were significantly higher than those of △^9-THC (3mg/kg, i.v.). These results may indicate the necessity to reconsider the present regulations on marihuana.

In this review, we would outline the possible signaling system for three types of amino acids including glutamate (Glu), γ-aminobutyric acid (GABA) and D-serine (D-Ser) to play a role as an extracellular signal mediator in mechanisms underlying maintenance of the cellular homeostasis in skeletal tissues. Although Glu and GABA has been thought to be an excitatory/inhibitory amino acid neurotransmitter in the mammalian central nervous system, our molecular biological analyses give rise to a novel function for Glu and GABA as an autocrine and/or paracrine factor in three types of distinct cell types including osteoblasts, osteoclasts and chondrocytes in bone tissues. Moreover, D-Ser plays a pivotal role in osteoclastogenesis through a mechanism related to the incorporation of serine enantiomers in osteoclasts after the synthesis and subsequent release from adjacent osteoblasts. Accordingly, bone formation and maintenance seems to be under control by amino acid signaling in skeletal tissues as seen with neurotransmission in the brain.

In Japan, a pharmacy or drug store license is required for selling pharmaceutical products. However, civilians without a pharmacy or drug store license are displaying pharmaceutical products for sale on a flea market application, which is illegal dealing. This study discussed the modality for implementing countermeasures for the illicit selling of pharmaceutical products. We extracted pharmaceutical products displayed for sale on three flea market applications (Mercari, Rakuma, Fril) on one day. One hundred and eighty-one pharmaceutical products were displayed (49 on Mercari, 86 on Rakuma, and 46 on Fril). There were 6.1% (11/181) domestically prescribed drugs, 69.1% (125/181) domestic over-the-counter (OTC) drugs, 23.8% (43/181) foreign-made prescribed drugs, and 1.1% (2/181) foreign-made OTC drugs. The seller could display the product for sale without confirming whether it is prohibited. We alerted the service providers of this illicit selling at flea markets at three different instances. The pharmaceutical product displays were deleted by the service providers at a rate of 55.1% (27/49) for Mercari and 51.2% (44/86) for Rakuma. The average number of drugs that were displayed for sale by each seller was 1.4 and the average number of total products that were displayed for sale by each seller was 100. The seller could have unintentionally displayed the pharmaceutical products for sale, without the knowledge that it is illegal. The service providers of flea market applications should create mechanisms to alert the sellers that displaying pharmaceutical products for sale is an illicit act and regulate these violations.

Lipid component, extracted from dried cells of Torulopsis utilis was examined by means of chromatography. It was found that lipid content in dried cells was 3% and this lipid consisted mainly of phospholipid (84%), which was largely composed of lecithin, phosphatidylethanolamine and lysolecithin, however neutral lipids are formed mainly of free fatty acid, triglyceride and sterol.Analysis of the fatty acid composition of the isolated lipid fractions by gas-liquid chromatography showed that acid neutral lipids and phospholipids contained mainly linoleic acid, oleic acid and palmitic acid, while free fatty acid fraction had a very low content of linoleic acid. The lysolecithin fraction contained considerably larger amounts of linoleic acid than the other lipid fractions.

Antibody-dependent cellular cytotoxicity (ADCC), a lytic attack on antibody-targeted cells, is triggered upon binding of lymphocyte receptors (FcγRs) to the antibody constant region. ADCC is considered to be a major therapeutic function of antibodies. ADCC requires the presence of oligosaccharides in the Fc region and is sensitive to change in the oligosaccharide structure. We have demonstrated that fucose is the most critical IgG1 oligosaccharide component, and the removal of fucose from IgG1 oligosaccharides results in a very significant enhancement of ADCC and anti-tumor activity in vivo. Many therapeutic antibodies approved or clinical development are produced using Chinese hamster ovary (CHO) cells that express high level of α1,6-fucosyltransferase and consequently produce highly fucosylated antibodies. We have established the fucosyltransferase knockout CHO cells which could stably produce non-fucosylated antibodies, designated as Potelligent antibodies. Potelligent antibodies show potent ADCC upon target cells through the effective and antigen-specific activation of NK cells due to augmented binding to FcγRIIIa. Moreover, Potelligent antibodies can evade the inhibitory effect of plasma IgG on ADCC through its high FcγRIIIa binding. Thus, the application of Potelligent antibodies is expected to be a promising approach as next-generation therapeutic antibodies with improved efficacy, even when administered at low doses in humans in vivo.

The purpose of this study was to develop and validate estimate equations for preventing adverse drug reactions (ADRs). We conducted five case-control studies to identify individual risk factors and subjective symptoms associated with the following five ADRs: drug-induced ischemic heart disease; renal damage; muscle disorder; interstitial pneumonia; and leucopenia. We performed logistic regression analysis and obtained eight regression equations for each ADR. We converted these to ADR estimate equations for predicting the likelihood of ADRs. We randomly selected 50 cases with non-individual ADRs from the Case Reports of Adverse Drug Reactions and Poisoning Information System (CARPIS) database of over 65000 case reports of ADRs, and assigned these cases to a validation case group. We then calculated the predictive probability for 50 cases using the eight estimate equations for each ADR. The highest probability for each ADR was set as the probability of each ADR. If the probability was over 50%, the case was interpreted as ADR-positive. We calculated and evaluated the sensitivity, specificity, and positive likelihood ratio of this system. Sensitivity of the estimate equations for muscle disorder and interstitial pneumonia were ≥90%. Specificity and positive likelihood ratios of estimate equations for renal damage, interstitial pneumonia and leucopenia were ≥80% and ≥5, respectively. Our estimate equations thus showed high validity, and are therefore helpful for the prevention or early detection of ADRs.

The metal dissociation constants of bovine carbonic anhydrase II, bovine carboxypeptidase A, rat aminopeptidase B, and rat dipeptidyl peptidase III were measured using metal buffer solutions. The zinc dissociation constants of bovine carbonic anhydrase II, bovine carboxypeptidase A, rat aminopeptidase B, and rat dipeptidyl peptidase III were 5.8×10−14, 3.5×10−12, 3.7×10−13, and 1.9×10−13 M, respectively. The ternary complex between metal derivatives of bovine carbonic anhydrase and various chelating agents were characterized using the kinetic method and visible and magnetic circular dichroism spectra. The coordination geometry of the ternary complex was in the equilibrium state between the five and the tetrahedral coordination geometry. The equilibrium state depends on the character of ligands. Dipeptidyl peptidase III which has an abnormal zinc binding motif (HEXXXH) was characterized using the point mutation and computer simulation methods. The abnormal zinc binding motif (HEXXXH) of rat dipeptidyl peptidase III has a large helix part. It is generally known that the cupric derivatives of the zinc peptidase loses enzyme activity, but the cupric derivative of dipeptidyl peptidase III surprisingly has enzyme activity. The measurement of the electron paramagnetic resonance spectra of the cupric rat dipeptidyl peptidase III in the presence of the substrate showed that the coordination geometry is very flexible. The flexibility of the coordination geometry in the cupric rat dipeptidyl peptidase III is important for the expression of enzyme activity. Docking simulation was used to identify the substrate binding site of aminopeptidase B, which is a powerful tool to estimate substrate binding residues in enzymes.

Diabetic patients exhibit increased blood plasma levels of methylglyoxal (MG), a metabolite of glucose. Since MG generates advanced glycation end-products (AGEs) that disrupt the functions of such biomolecules as proteins, it is responsible for the progression and complications of diabetes. A functional disorder of the vascular endothelium may also contribute to the progression and complications of diabetes. In endothelial cells, MG is the major precursor for the formation of AGEs. In this study, we examined the effects of MG on vascular endothelial cells and found that it induced the apoptosis of bovine aortic endothelial cells (BAECs). MG induced the collapse of mitochondrial membrane potential, an index of apoptosis, and the elevation of caspase-3 activity, an apoptotic execution enzyme, leading to cell death. Flow cytometric analyses with annexin-V and propidium iodide double staining revealed that cells exposed to a lethal dose of MG displayed features characteristic of apoptosis. MG induced an increase in the level of intracellular reactive oxygen species (ROS) prior to induction of apoptosis. Taken together, these findings suggest that BAECs exposed to MG die by apoptosis due to the increase of intracellular ROS level.

As a new strategy for drug discovery and development, we propose here the establishment of drug re-profiling strategy. In this strategy, the actions of existing medicines, whose safety and pharmacokinetic effects in humans have been confirmed already, are examined comprehensively at the molecular level and the results are used for the development of new medicines. For example, identification of the mechanisms underlying the side effects of medicines enables us to develop safer drugs. The results can also be used for developing existing drugs for use as medicines in treatment of other diseases. Promoting this research strategy could provide breakthroughs in drug discovery and development by pharmaceutical companies.

The rate of smoking in patients with schizophrenia is higher than that in the general population. Nicotinic acetylcholine receptors (nAChR) are involved in the sensorimotor gating deficits in schizophrenia. We have revealed that nicotine ameliorates the disruption of the PPI, a model of sensorimotor gating, which is induced by apomorphine, a dopamine receptor agonist, but is not effective for the disruption of the PPI induced by phencyclidine, a glutamine NMDA receptor antagonist, in rats. Furthermore, the ameliorating effect of nicotine is antagonized by methyllycaconitine, a selective α_7 nAChR antagonist. The effect of nocitine was also investigated in the stereotyped behavior induced by apomorphine, however, nicotine was found to have no significant effect. Considering these results, the ameliorating effect of the disruption of the PPI via α_7 nAChR is therefore thought to be involved in dopaminergic systems. The dopaminergic systems involved in α_7 nAChR may be different from the systems involved in stereotypy. In addition, this review describes the effects of the α_7 nicotinic receptor agonists.

Recently, extended-spectrum β-lactamase (ESBL)-producing Escherichia coli has been more frequently isolated from blood specimens than in the past. In this study we investigated a panel of therapeutic agents used to treat 37 patients with ESBL-producing E. coli bacteremia. Antimicrobial agents administered as definitive therapy displayed higher efficacy rates than when empiric therapy was administered (efficacy rates, 95.7% vs. 62.5%). The success rate of carbapenem was 95.8% (23/24) in patients with ESBL-producing E. coli bacteremia. In addition, the success rate of cefmetazole against ESBL-producing E. coli sensitive to this drug was 87.5% (7/8). In conclusion, patients at high risk of infection due to ESBL-producing E. coli should be empirically treated with carbapenem antibiotics. In addition, cefmetazole may be a treatment option for patients with ESBL-producing E. coli bacteremia.

Although the removal of bacteria in the oral cavity is regarded as an important preventive measure against pneumonia, the majority of elderly individuals are rarely provided with oral care-related information. This study examined the usefulness of oral care-related information provision for the elderly by pharmacists working at drugstores. A questionnaire survey was conducted, involving 387 pharmacists working at drugstores and 51 elderly individuals who visited such stores. Oral care-related information had been actively provided by 14.5% of the pharmacists, and 62.5% of all oral care products were being sold as care products. When focusing on the elderly, 70.6% showed interest in oral care, but the proportion of those who had performed self-care to promote such health was limited to 5.9%. After being provided with oral care-information, 97.6% answered “I wish to regularly perform oral self-care”, and 86.3% regarded oral care-related information provision by pharmacists as “very useful”. The results of this study demonstrate the usefulness of information provision by pharmacists at drugstores to promote oral self-care among the elderly.

Considerable attention has focused on cannabidiol (CBD), a major non-psychotropic constituent of fiber-type <i>cannabis</i> plant, and it has been reported to possess diverse biological activities. Although CBD is obtained from non-enzymatic decarboxylation of its parent molecule, cannabidiolic acid (CBDA), several studies have investigated whether CBDA itself is biologically active. In the present report, the author summarizes findings indicating that; 1) CBDA is a selective cyclooxygenase-2 (COX-2) inhibitor, and ii) CBDA possesses an anti-migrative potential for highly invasive cancer cells, apparently through a mechanism involving inhibition of cAMP-dependent protein kinase A, coupled with an activation of the small GTPase, RhoA. Further, the author introduces recent findings on the medicinal chemistry and pharmacology of the CBD derivative, CBD-2′,6′-dimethyl ether (CBDD), that exhibits inhibitory activity toward 15-lipoxygenase (15-LOX), an enzyme responsible for the production of oxidized low-density lipoprotein (LDL). These studies establish CBD as both an important experimental tool and as a lead compound for pharmaceutical development. In this review, the author further discusses the potential uses of CBD and its derivatives in future medicines.<br>

We established dose estimation formulae for renal-excretion drugs using the glomerular filtration rate (GFR), tubular secretion clearance (Sc), and unbound fraction of drug in plasma (fp) as a renal function index of physiological development in neonates and infants not more than 2 years of age. A dose ratio of (D_C/D_A)=clearance ratio of (CL_C/CL_A)≅(fp_C·GFR_C)/(fp_A·GFR_A) for neonates and infants/adults was applied to drugs with fp·GFR>Sc, while D_C/D_A=CL_C/CL_A≅(β·BSA_C+fp_C·GFR_C)/(β·BSA_A+fp_A·GFR_A) was applied to drugs with Sc>fp·GFR using the coefficient of each drug (β) and body surface area (BSA). Validity of the estimation formulae was investigated in drugs with fp·GFR>Sc such as vancomycin (VCM), arbekacin (ABK), fosfomycin (FOM) and norfloxacin (NFLX), and in drugs with Sc>fp·GFR such as digoxin (DGX) and amoxicillin (AMPC). First, we compared the clearance ratio (CL_C/ CL_A) of VCM, ABK, and DGX estimated by our method with those calculated using the Japanese population clear- ance values and those estimated allometrically (BSA_C/BSA_A). Next, we compared the established doses of all drugs investigated with the doses for neonates and infants calculated from the conventional dose estimation methods for children and our estimation formulae, and evaluated our method. As a result, favorable consistency was observed in the CL ratio for all drugs, and the doses of VCM, FOM, NFLX and AMPC calculated from our estimation formulae approximated the established doses. In conclusion, the validity of the dose estimation method using pharmacokinetic factors related to physiological development (i.e., GFR, fp, Sc) for renal-excretion drugs in neonates and infants was demonstrated.<br>
