Recent advances in the research of broad-spectrum antiviral agents / 药学学报

Viral infections have always threatened human health. Broad-spectrum antiviral agents (BSAs) can either target host proteins that are essential for viral replication, or act on multiple viruses or multiple genotypes of the same virus. More importantly, BSAs could reduce the possibility of drug resistance. From the perspective of medicinal chemistry, this review summarizes recent advances in the research of broad-spectrum antiviral drugs with privileged structures or targeting specific targets in the viral life cycle.

Discovery of lead compounds to inhibit proliferation of cervical cancer cells based on privileged structure of 6,11-dihydro-5H-benzoacarbazole / 上海交通大学学报（医学版）

Objective·To discover lead compounds with 6,11-dihydro-5H-benzo[a]carbazole as core scaffold that can inhibit the proliferation of cervical cancer cells. Methods?·?A series of 6,11-dihydro-5H-benzo[a]carbazole derivatives and analogs were synthesized using Fischer indole synthesis method, and their anticancer activity against HeLa cells was tested in vitro by CCK8 test. Results?·?2-Methoxy-6,11-dihydro-5H-benzo[a]carbazole and 8-chloro-2-methoxy-6,11-dihydro-5H-benzo[a]carbazole could significantly inhibit the proliferation of HeLa cells with the half maximal inhibitory concentration ( IC50) values of 9.61?μmol/L and 16.52?μmol/L, respectively. Conclusion?·?Two objective lead compounds were found. Among 6,11-dihydro-5H-benzo[a]carbazole derivatives, compounds with methoxy group at the C-2 position of the core scaffold show better activity against proliferation of cervical cancer cells.
