The coronavirus disease 2019 (COVID-19) virus is spreading rapidly, and scientists are endeavoring to discover drugs for its efficacious treatment in China. Chloroquine phosphate, an old drug for treatment of malaria, is shown to have apparent efficacy and acceptable safety against COVID-19 associated pneumonia in multicenter clinical trials conducted in China. The drug is recommended to be included in the next version of the Guidelines for the Prevention, Diagnosis, and Treatment of Pneumonia Caused by COVID-19 issued by the National Health Commission of the People's Republic of China for treatment of COVID-19 infection in larger populations in the future.

The SARS-CoV-2 virus emerged in December 2019 and then spread rapidly worldwide, particularly to China, Japan, and South Korea. Scientists are endeavoring to find antivirals specific to the virus. Several drugs such as chloroquine, arbidol, remdesivir, and favipiravir are currently undergoing clinical studies to test their efficacy and safety in the treatment of coronavirus disease 2019 (COVID-19) in China; some promising results have been achieved thus far. This article summarizes agents with potential efficacy against SARS-CoV-2.

Drugs that are specifically efficacious against SARS-CoV-2 have yet to be established. Chloroquine and hydroxychloroquine have garnered considerable attention for their potential to treat coronavirus disease 2019 (COVID-19). Increasing evidence obtained from completed clinical studies indicates the prospects for chloroquine/hydroxychloroquine to treat COVID-19. More randomized control clinical studies are warranted to determine the feasibility of these two drugs in treating COVID-19.

The Ebola outbreak in West Africa this year is causing global panic. The high mortality of this disease is largely due to lack of effective preventive vaccines or therapeutic drugs. Realizing the gravity and urgency in controlling the epidemic, governments and drug companies across the world have taken many strong measures to speed up the process of drug development. Several representative candidate drugs that demonstrate potent anti-Ebola activity in preclinical studies have been pushed forward to higher research stages to obtain an earlier official license. It is expected that proven preventive or therapeutic regimens could be established in the near future.

Histone deacetylase is an important member of epigenetics and a well validated target for anti-cancer drug discovery. In this study, we designed and synthesized a series of twenty-one novel hydroxamic acid-based histone deacetylase inhibitors with 4-piperidin-4-yl-triazole as the core skeleton. Most target compounds displayed excellent inhibition rates toward histone deacetylases at the concentration of 1 μM. Among them, the inhibition rates of two compounds MH1-18 and MH1-21 exceeded 90%. Furthermore, these two compounds selectively inhibited the activity of histone deacetylase 6 with low IC50 values. The high potency of them toward histone deacetylase 6 was rationalized by molecular docking studies. We found that MH1-18 and MH1-21 moderately inhibited the proliferation of four human cancer cell lines SGC-7901, NCI-H226, MCF-7, and HL-60. However, MH1-21 showed potent efficacy in suppressing the migration of MCF-7 cells. Results obtained in the current study shed light on designing potent HDAC6 inhibitors as anti-cancer agents.

Resveratrol (3, 5, 4'-trihydroxystilbene) is a phytoalexin contained in a variety of plants, such as grapes, berries and especially in the dried roots of Polygonum cuspidatum Sieb. et Zucc. It has been shown to exhibit anti-oxidative and anti-inflammation activity, and to reverse the effects of aging. Its ability to suppress cell proliferation, induce apoptosis and suppress the metastasis and invasion in a number of cell lines has prompted a large interest from people for its use as an anti-tumor component. In this review, evidence of resveratrol's anti-tumor effects and molecular mechanisms are recapitulated. First, we present the anti-apoptosis, anti-invasion/metastasis and anti-inflammation effect of resveratrol; second, the main signaling pathways involved in these activities are described and summarized with the studies of different tumors involved. Resveratrol not only induces apoptosis of tumor cells through intrinsic/extrinsic pathways and cell cycle arrest, but also inhibits the invasion and metastasis abilities of tumors via modulating collagen degradation-related molecular targets. Altogether, the present findings suggest the anti-tumor potential of resveratrol against various types of cancers.

ABSTRACT: Numerous studies have documented that in cancer therapy flavonoids extracted from traditional Chinese medicine have anti-tumor activity or can enhance efficiency of chemotherapy in combination with chemotherapeutics. Thus, an awareness of flavonoids is needed by physicians and medical researchers. This review provides evidence about anti-hepatocellular carcinoma activity of flavonoids. First, as a common employed in vitro model, profile of HepG2 is shown. Second, the intracellular signaling pathways induced by flavonoids which inhibit the HepG2 cell line are summarized. Third, study situation of anti-HBV/HCV activity of flavonoids is shown. Our review is aimed at providing an understanding of anti-HBV/HCV activity and anti-HCC mechanisms of flavonoids, and an outlook on flavonoids application on cancer therapy.
