- THE FIRST BRANCHED BENZOXAZINOPHENOTHIAZINE RING SYSTEM AND ITS AZA-ANALOGUES
-
The synthesis of a branched benzoxazinophenotiazine heterocycle is described.The parent compound benzo-benzoxazinophenothiazine (12), was obtained from 2,3-dichloro-1,4-naphthoquinone (6), 2-aminophenol and 2-aminothiophenol.Monoaza-, diaza- and triaza- analogues of this novel heterocycle were also synthesized.The parent compounds, 16-oxa-15-thia-4,5,10,14-tetraazabenzopentaphene (18) and 16-oxa-15-thia-4,5,10,14-tetraazabenzopentaphene (22, R=H) were also synthesized as well as 4-amino-16-oxa-15-thia-4,5,10,14-tetraazabenzopentaphene (24).They are intensely coloured high-melting solids suitable for application as pigments.Their ease of reduction with Na2S2O4 and the ready oxidation of the reduced compounds to applicability also as vat dyes.

- Synthesis and antifungal activity of novel thiazole-containing triazole antifungals. II. Optically active ER-30346 and its derivatives
-
A series of novel thiazole-containing triazole antifungals was synthesized and evaluated for antifungal activity against a variety of clinically isolated pathogenic fungi in vitro and against systemic candidosis in vivo. These compounds showed potent antifungal activities in vitro and in vivo. In particular, (2R,3R)-3-[4-(4-cyanophenyl)thiazol-2-yl]-2-(2,4- difluorophenyl)-1-(1H-1,2,4-triazol-l-yl)-2-butanol (12g; ER-30346) showed potent and well-balanced in vitro activities and potent in vivo efficacy, and had a good safety profile.

-
The reaction of 2-mercapto-3-ureido- and 2-mercapto-3-aminopyridines with β-halo derivatives of carbonyl compounds (ketones, acids, and aldehydes) and with acrylonitrile proceeds not only via the mercapto group but also via the amino group, as a result of
