Isatin-β-thiosemicarbazones as potent herpes simplex virus inhibitors
摘要:
A series of isatin-beta-thiosemicarbazones have been designed and evaluated for antiviral activity against herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) in a plaque reduction assay. Their cytotoxicity was examined using human rhabdomyosarcoma cells (RD cells). Several derivatives of isatin-beta-thiosemicarbazone exhibited significant and selective antiviral activity with low cytotoxicity. It was found that the thiourea group at thiosemicarbazone and the NH functionality at isatin were essential for their anti-herpetic activity. The synthesis and structure-activity relationship studies are presented. (C) 2011 Elsevier Ltd. All rights reserved.

A series of 3‐(arylthiosemicarbazono)‐2‐indolinones 1, 1‐methyl‐3‐(arylthiosemicarbazono)‐2‐indolinones 2 and 1‐(aminomethyl)‐3‐(arylthiosemicarbazono)‐2‐indolinones 3 have been synthesised. All compounds were screened for their antiviral activity against Sunnhemp rosette virus (SRV) in vitro as well as in vivo. Twelve compounds show significant antiviral activity.

A series of isatin‐β‐thiosemicarbazones and isatin‐β‐hydrazonothiazolines was synthesized by condensation of various isatin derivatives with N4‐substituted 3‐thiosemicarbazides and cyclization of the products by phenacyl bromides. The products showed high toxicity at lower concentrations when tested for antiviral activity against MDCK cells and did not exhibit antimicrobial activity against various
