Synthesis of Substituted 4H-Thienobenzothiopyran-4-ones as Possible Schistosomicidal Agents

El-Kerdawy, Mohamed M.,El-Emam, Ali A.,El-Subbagh, Hussein I.,Abushanab, Elie

, p. 45 - 50 (2007/10/02)

A new series of thiophenic isosters of thioxanthones, namely: 2-substituted-4H-thienobenzothiopyran-4-ones and 5-substituted-2-nitro-8-methyl-4H-thienobenzothiopyran-4-ones were synthesized as potential schistosomicidal agents.The synthesized compounds were characterized by their 1H-NMR data.
