“…The five-membered 1,3-thiazolidin-4-ones are known to have a broad array of biological activity (Jain, Vaidya, Ravichandran, Kashaw & Agrawal, 2012, Abhinit, Ghodke & Pratima, 2009, Hamama, Ismail, Shaaban & Zoorob, 2008, Singh, Parmar, Raman & Stenberg, 1981, Brown, 1961, Tripathi et al, 2014, Prabhakar, Solomon, Gupta & Katti, 2006. Compounds in this family include active pharmaceuticals thiazolidomycin (anti-streptomyces species), pioglitazone (hypoglycemic for treatment of diabetes), etoziline (anti-hypertensive), and ralitoline (anti-convulsant) (Brown, 1961, Tripathi et al, 2014. The six-membered 1,3-thiazin-4-ones have also often been investigated for their biological activity (Ryabukhin, Korzhavina & Suzdalez, 1996) and include the anti-anxiety and muscle relaxant drugs chlormezanone (Ryabukhin et al, 1996, Tanaka & Hirayani, 2005, Surrey, Webb & Gesler, 1958 and dichlormezanone (Surrey, et al, 1958).…”
