Thiazole derivatives
R 0260
Preparation of New Derivatives of Thiazole, Thiazolidine, and Thiazol-2-ylpyraSulfonamido Conjugates. — The title derivatives are pre08- 127 zolo[3,4-D]pyrimidine
pared from the piperidinesulfonylacetophenones (II) and (IX) as starting materials, and
selected compounds are screened for their antibacterial and antifungal activities. The
title sulfonamido conjugates display improved biological properties with respect to the
nonsulfonamido-conjugated thiazoles. The most active compounds against K. pneumonia, Rhizopus fungi, and A. fumigatus are (Vb), (VIII), and (VIIc), respectively. Compounds (IIIa), (VIIa), (XIa), (XIb), and (XIII) are slightly less active. All remaining
compounds are weakly active against all of the tested microorganisms. —
