, p. 995 - 998 (2007/10/03)
Leinamycin, an antitumor antibiotic isolated from Streptomyces sp., shows a 1,2-dithiolan-3-one 1-oxide heterocycle that appears to be involved in the biological activity. Several derivatives related to 1,2-dithiolan-3-one 1-oxide have been prepared and their activity as antineoplastic agents have been investigated. The synthesized compounds did not display a significative antitumor or cytotoxic activity in vitro.

A series of 2-substituted isothiazolo[5,4-b]pyridine-3(2H)-thiones, isothiazolo[5,4-b]pyridin-3(2H)-ones, N-substituted 2-sulfanylnicotinamides and the corresponding carbothioamide derivatives were synthesized and evaluated for their antimicrobial activity against several strains of Gram+ and Gram-bacteria and fungi. Chemical syntheses were resumed into a comprehensive cyclic route that enables the reversible conversion for each derivative of the series considered. Among the tested compounds the N-(aralkyl)-2-sulfanylnicotinamides show the highest fungitoxicity (MIC=1.25-5 μg/ml). The best activity towards Gram-positive bacteria was in the range of 2.5-5 μg/ml. Activity against Gram-negative bacteria was generally very poor for all compounds. Copyright

Baggaley, Keith H.,Jennings, L. John A.,Tyrrell, A. William R.
, p. 1393 - 1396 (2007/10/02)
The synthesis of some 2-substituted derivatives 1-4 of all four isomeric isothiazolopyridin-3-ones is described.Several novel 1,2-dithiolopyridin-3-ones and 3-thiones were prepared as intermediates.
