Trachelospermi caulis is used widely as an herbal medicine in oriental countries to attenuate fever and pain. We wished to reveal the novel function of this herb and its active component on barrier function in intestinal epithelial cells. Monolayers of intestinal epithelial cells (Caco-2) were used to evaluate the transepithelial electrical resistance (TEER) and quantity of permeated ovalbumin (OVA) as indices of barrier function. T. caulis increased TEER values on cell monolayers and decreased OVA permeation across cell monolayers. To ascertain the active component of T. caulis, the extract was isolated to five fractions, and the effect of each of these fractions on intestinal barrier function examined. Chloroform and ethyl acetate fractions showed increased TEER values and decreased OVA flux. Chloroform and ethyl acetate fractions contained mainly trachelogenin and its glycoside, tracheloside. Trachelogenin increased TEER values and decreased OVA flux by enhancing the tight-junction protein occludin (but not tracheloside) in Caco-2 monolayers. These findings demonstrated that trachelogenin, an active component of T. caulis, might help to attenuate food allergy or inflammatory bowel disease through inhibition of allergen permeation or enhancement of the intestinal barrier.

We investigated a method for the simultaneous screening, identification, and quantitative determination of salicylic acid, acetaminophen, theophylline, barbiturates, and bromvalerylurea, drugs that frequently cause acute poisoning in Japan and therefore require rapid analysis for effective treatment in the clinical setting. The method employs liquid chromatography/electrospray mass spectrometry (LC/MS) of solid-phase extracted serum samples. For LC/MS ionization, the electrospray-ionization method was used, with acetaminophen in the positive-ion mode, and salicylic acid, theophylline, phenobarbital, bromvalerylurea, pentobarbital, amobarbital, and o-acetamidophenol (internal standard) in the negative-ion mode, the base ions were used in each case for quantitative analysis. Quantitation was possible for the following sample concentration ranges: salicylic acid and acetaminophen, 100 to 5 μg/ml; theophylline, 100 to 0.5 μg/ml; and phenobarbital, bromvalerylurea, pentobarbital, and amobarbital, 100 to 1 μg/ml. Using full-scan mass spectrometry, the lower detection limits of 1 μg/ml for salicylic acid and acetaminophen, 0.1 μg/ml for theophylline, and 0.5 μg/ml for phenobarbital, bromvalerylurea, pentobarbital, and amobarbital were adequate for identifying acute poisoning. When each compound was added to serum to a final concentration of 5 μg/ml and solid-phase extraction was performed using Oasis HLB 1-cc (30-mg), the mean recovery rate of each compound was 89.2 to 96.1% (n=5), and the coefficients of variation of the intraday and interday assays were 3.55 to 6.05% (n=5) and 3.68 to 6.38% (n=5), respectively, which are acceptable. When this method of analysis was applied in testing the sera of a female patient who had consumed a large amount of an unknown commercial drug, salicylic acid and bromvalerylurea were identified, and the treatment strategy could be determined in accordance with the serum concentration of those drugs.

A new solvent system benzene-n-hexane-diethylamine (25 : 10 : 1), was found to show a good separation of cannabidiol, tetrahydrocannabinol and cannabinol in hemp resin by thin-layer chromatography, in which Rf-values of three constituents were 0.45, 0.35 and 0.25, respectively. Furthermore, the same solvent system was successfully applied to silica gel column chromatography for isolation of three constituents of hemp resin. Using cocaine hydrochloride as an internal standard of gas chromatography, relative retention times of cannabidiol, tetrahydrocannabinol and cannabinol were calculated to be 1.76, 2.34 and 2.88, respectively. Six kinds of hemps grown in India, U.S.A. and Japan, were quantitatively analyzed using gas chromatography, and against a common opinion, Japanese hemps were found to contain considerable amounts of tetrahydrocannabinol, a physiologically active constituent.

&nbsp;&nbsp;Nucleosides and nucleotides are one of the most important elements for cells by the fact that they are components of DNAs and RNAs. In addition, they play important roles in most fundamental cellular metabolic pathways such as energy donors, second messengers, and cofactors for various enzymes. Therefore, there exists a rich source in drug discovery targeting nucleosides and nucleotides. In order to utilize nucleosides and nucleic acids on the drug development, it is very important to develop reactions and methods, by which the highly coordinating and labile nucleoside intermediates can be used. With these in mind, we have been working on synthetic nucleoside and nucleic acid chemistry. First, branched sugar nucleoside derivatives, which are potential antitumor agents, have been synthesized utilizing samarium diiodide (SmI<sub>2</sub>) mediated Reformatsky reaction or aldol reaction. 3&prime;-&beta;-Carbamoylmethylcytidine (CAMC) was found to exhibit potent cytotoxicity against various human tumor cell lines. Synthetic methodology of the caprazamycins, which are promising antibacterial nucleoside natural products, was also developed by the strategy including &beta;-selective ribosylation without using a neighboring group participation. Our synthetic route provided a range of key analogues with partial structures to define the pharmacophore. Simplification of the caprazamycins was further pursued to develop diketopiperazine analogs. Medicinal chemistry of oligodeoxynucleotides has been conducted. Thus, novel triazole-linked dumbbell oligodeoxynucleotides and modular bent oligodeoxynucleotides were synthesized. They exhibit excellent binding affinity to NF-&kappa;B or HMGB1 A-box protein, which are important therapeutic targets. Therefore, the results obtained conclusively demonstrated these oligodeoxynucleotides could be proposed as powerful decoy molecules.<br>

Cephalothine sodium (CET-Na) in crystals can be obtained by freezing the aqueous solution and subsequent warming at a fixed temperature for facilitating crystallization prior to vacuum application for drying. The product has, however, been found to unavoidably contain traces of the amorphous CET-Na, which causes a rapid color development during storage. By using thermal analysis, differential scanning calorimetry (DSC), electric conductometry, and polarized light cryomicrographic techniques, the solubilities in water, freezing point, eutectic point, and melting behavior of CET-Na in aqueous solution were investigated. The investigation demonstrated that CET-Na in supersaturated aqueous solution is very stable, and that seeding with microcrystalline CET-Na to the supersaturated solution and subsequent cooling of the mixture till its freezing point gives neither any evidence for crystallization nor for growth of the seed crystals. The freeze-drying of CET-Na in the supersaturated solution after seeding has been demonstrated to give crystalline CET-Na contaning neither of amorphous nor of quasicrystalline form.

A hydroxylated metabolite of 1-(tetrahydro-2-furanyl)-5-fluorouracil (FT), 1-(trans-3-hydroxytetrahydro-2-furanyl)-5-fluorouracil (trans-3'-OH-FT, VIII) and its isomer, 1-(cis-3-hydroxytetrahydro-2-furanyl)-5-fluorouracil (cis-3'-OH-FT, VI), were synthesized and isolated at high purity. As compounds related to FT metabolites, 2, 3'-anhydro-1-(cis-3-hydroxytetrahydro-2-furanyl)-5-fluorouracil (2, 3'-anhydro-FT, V), 1-(2, 5-dihydro-2-furanyl)-5-fluorouracil (3', 4'-dehydro-FT, XII) and 1-(5-acetoxytetrahydro-2-furanyl)-5-fluorouracil (5'-AcO-FT, XI) were also synthesized. The antitumor activities of these compounds against sarcoma 180 and L 1210 were examined. The activities of cis-3'-OH-FT (VI) and 2, 3'-anhydro-FT (V) were found to be lower than that of FT. The activity of 5'-AcO-FT (XI) was the same as that of FT. 3', 4'-Dehydro-FT (XII) showed much greater activity than FT.

Six types of 5-fluorouracil (5-FU) derivatives were synthesized ; namely, 2,4-di-O-substituted, 2-O-substituted, 4-O-substituted, 1,3-disubstituted, 1-substituted and 3-substituted compounds. After oral administration of these compounds to rats, the blood levels of 5-FU were determined. Among O-substituted derivatives, a 4-O-substituted derivative was most easily activated to 5-FU and 2-O-substituted derivatives were next most easily activated. Among N-substituted derivatives, acyl and sulfonyl derivatives showed the highest 5-FU releasing abilities and 1-alkoxymethyl substituted derivatives showed low ability. N-Alkyl substituted derivatives were not activated to 5-FU. Several compounds which gave higher blood levels of 5-FU than that obtained with 1-(tetrahydro-2-furyl)-5-fluorouracil (Thf-FU), as well as same related compounds, were selected and their antitumor activities were examined. The 2-O-substituted derivatives, 2-butoxy-5-fluoro-4 (1H)-pyrimidone (11) and 2-benzyloxy-5-fluoro-4 (1H)-pyrimidone (19), were as effective as Thf-FU. The activities of 2,4-di-O-substituted derivatives, 2,4-dibutoxy-5-fluoropyrimidine (1) and 2,4-dibenzyloxy-5-fluoropyrimidine (6), against Ehrlich carcinoma and against sarcoma 180,respectively, were the same as those of Thf-FU. The 1-substituted derivatives, 1-ethoxymethyl-5-fluorouracil (49) and 1-(1-ethoxy-1-phenylmethyl)-5-fluorouracil (50), were found to be as effective as Thf-FU.

The mechanism of the condensation of 5-fluorouracil and 2-acetoxytetrahydrofuran (3), giving 1-(tetrahydro-2-furyl)-5-fluorouracil, was studied. An equilibrium between 2-acetoxytetrahydrofuran (3) and 2,3-dihydrofuran (4) was observed at 120-170℃ in dimethylformamide. It was found by the use of 1,3-dideuterio-5-fluorouracil that the condensation of 5-fluorouracil with 3 occurred both by direct substitution and by the formation of 4 from 3 followed by addition of the uracil to it. The contribution of the latter path increased with increase of the reaction temperature.

Various O-acyl and N-acyl derivatives of 2'-deoxy-5-trifluoromethyluridine (F_3Thd) were synthesized; namely 5'-O-acyl, 3',5'-di-O-acyl, N^3-acyl, 3',5'-di-O-acetyl-N^3-acyl, 3',5'-di-O-carbamoyl and 3',5'-di-O-ethoxycarbonyl compounds. 5'-O-Acyl derivatives of 2'-deoxy-5-trifluoromethylcytidine were also synthesized. The antitumor activities of these compounds against sarcoma 180 were examined by oral administration to mice. Among the 5'- and 3',5'-diester compounds with aliphatic acids, the 5'-O-hexanoyl compound showed the highest activity. Full protection of the sugar moiety with aroyl or carbamoyl groups considerably decreased the activities, and those of the 3',5'-di-O-m-fluorobenzoyl and 3',5'-di-O-butylcarbamoyl compounds were the smallest. N^3-Benzoyl compounds were slightly more effective than F_3Thd but none of them showed higher activity than the effective O-acyl compounds. In the case of 5'-O-acylates of 2'-deoxy-5-trifluoroniethylcytidine, the 5'-O-benzoyl compound showed the highest activity.

Various O-alkoxyalkyl derivatives of 2'-deoxy-5-trifluoroniethyluridine(F_3Thd) were synthesized, and the antitumor activities of the compounds against sarcoma 180 were examined by oral administration to mice. Among the formal-type derivatives, 3',5'-di-O-ethoxymethyl (3), 3',5'-di-O-benzyloxyinethyl (12), 5'-O-benzyloxymethyl (13) and 3'-O-benzyloxymethyl (14) compounds showed high activities, which were six-fold higher than that of F_3Thd itself. Since acetal-type derivatives were unstable under acidic conditions, antitumor testing of the compounds was also carried out with co-administration of sodium bicarbonate. 5 '-O-(1-Ethoxypropyl)-F_3Thd (25) and 5'-O-(1-benz:yloxypropyl)-F_3Thd (37) showed the highest activities among the acetal-type derivatives, but the ED_50 values of the compounds were not lower than those of effective formal-type compounds. These O-alkoxyalkyl derivatives of F_3Thd are resistant to degradation by thymidine phosphorylase and are activated by microsornal drug-metabolizing enzymes after absorption.

Piperazinealkanol ester derivatives of indomethacin were prepared and tested for inhibitory activities against 5-lipoxygenase (5-LO) and cyclooxygenase (CO). They inhibited 5-hydroxyeicosatetraenoic acid (5-HETE) formation by the cytosol of guinea pig polymorphonuclear leukocytes and thromboxane B_2 (TXB_2) formation by washed rabit platelet suspension. Of the test compounds, 2-[4-(2-hydroxyethyl)-1-piperazinyl]-1-phenylethyl 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-3-indolylacetate dimaleate (II-8) was found to be the most active dual inhibitor of 5-LO and CO, and its inhibitory potency was higher than that of 2-[4-(3-hydroxypropyl)-1-piperazinyl]-ethyl [1-(4-chlorobenzoyl)-5-methoxy-2-methyl]-3-indolylacetate (CR-1015) (I), the lead compound.

Fetal liver (FL) hematopoiesis is thought to be important for expanding the cell number during ontogeny. In order to investigate the cellular interaction molecules among FL stromal and hematopoietic cells, we established a monoclonal antibody, Ndk-10, that reacts with FL stromal cells but not with dish non-adherent cells. When Ndk-10 was added to an FL stromal and hematopoietic cell-coculture, it inhibited the survival of c-kit+ cells. The inhibitory activity of Ndk-10 was also observed in the fetal liver organ culture. The Ndk-10 recognized a 150 kD molecule in the adherent cells of FL and kidney, and the N-terminal amino acid sequence was identical to that of mouse aminopeptidase N/CD13. The peptidase activity of CD13 was inhibited by Ndk-10, and addition of its specific inhibitor resulted in the same inhibitory activity as Ndk-10. We propose that aminopeptidase N/CD13 is a critical molecule that regulates the survival of c-kit+ cells in the FL microenvironment.

The onset of oral candidiasis is accompanied by inflammatory symptoms such as pain in the tongue, edema or tissue damage and lowers the quality of life (QOL) of the patient. In a murine oral candidiasis model, the effects were studied of terpinen-4-ol (T-4-ol), one of the main constituents of tea tree oil, Melaleuca alternifolia, on inflammatory reactions. When immunosuppressed mice were orally infected with Candida albicans, their tongues showed inflammatory symptoms within 24 h after the infection, which was monitored by an increase of myeloperoxidase activity and macrophage inflammatory protein-2 in their tongue homogenates. Oral treatment with 50 µL of 40 mg/mL terpinen-4-ol 3h after the Candida infection clearly suppressed the increase of these inflammatory parameters. In vitro analysis of the effects of terpinen-4-ol on cytokine secretion of macrophages indicated that 800 µg/mL of this substance significantly inhibited the cytokine production of the macrophages cultured in the presence of heat-killed C. albicans cells. Based on these findings, the role of the anti-inflammatory action of T-4-ol in its therapeutic activity against oral candidiasis was discussed.
