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.

Abstract Six new platinum(II) complexes of a thiosemicarbazone Schiff base with isatin moiety [PtL1 to Pt(L6)2] were synthesized by the reaction of platinum(II) with the following: (Z)-2-(2-oxoindolin-3-ylidene)-N-phenylhydrazinecarbothioamide [L1H], (Z)-2-(5-methyl-2-oxoindolin-3-ylidene)-N-phenylhydrazinecarbothioamide [L2H], (Z)-2-(5-fluoro-2-oxoindolin-3-ylidene)-N-phenylhydrazinecarbothioamide

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
pathophysiological functions of these enzymes are not fully understood due to lack of potent and selective NTPDase inhibitors. Herein, a series of oxoindolin hydrazine carbothioamide derivatives is synthesized and screened for NTPDase inhibitory activity. Four compounds were identified as selective inhibitors of h-NTPDase1 having IC50 values in lower micromolar range, these include compounds 8b (IC50 = 0.29 ± 0
