A series of 2,5,6-trisubstituted imidazo[2,1-b][1,3,4]-thiadiazole derivatives 4(a-k) have been prepared by reaction of 2-amino-5-cyclopropyl-1,3, 4-thiadiazole and an appropriate phenacyl bromide. Further 5-bromo 5(a-k) and 5-thiocyanato 6(a-k) derivatives were synthesized in order to study the effect of these substituents on antitumor activity. Structures of these compounds were established by IR, 1H NMR, 13C NMR and Mass spectroscopy. Seven compounds were granted NSC code at National Cancer Institute (NCI), USA for anticancer activity at a single high dose (10 -5 M) in full NCI 60 cell panel. Among the compounds tested, 5-bromo-6-(4-chlorophenyl)-2- cyclopropylimidazo[2,1-b][1,3,4]thiadiazole 5b (NSC D-96022/1) was found to be the most active candidate of the series at five dose level screening with degree of selectivity toward Leukemic cancer cell line. © 2011 Elsevier Masson SAS.

Gum ghatti (Anogeissus latifolia) or Indian gum is a complex non-starch polysaccharide. It has been widely employed in food, pharmaceuticals, paper and other industries primarily due to its excellent emulsification and thickening property. Other applications of gum ghatti are inadequately investigated owing to lack of information on it. Researchers in the recent years have shown a great interest in exploring its molecular structure and functional properties. This article is aimed at discussing the structural features, functional properties and applications of gum ghatti with an emphasis on its pharmaceutical potential. © 2011 Elsevier Ltd.

A series of 1-methyl-N-[(substituted-phenylmethylidene)-1H-benzimidazol-2-amines (4a-4g) were prepared via the formation of 1-methyl-1H-benzimidazol-2-amine (3), which was prepared by the cycloaddition of o-phenylenediamine (1) with cyanogen bromide in the presence of aqueous base followed by N-methylation with methyl iodide in the presence of anhydrous potassium carbonate in dry acetonitrile. Moreover, the four-membered β-lactam ring was introduced by the cycloaddition of 4a-4g and chloroacetyl chloride in the presence of triethylamine catalyst to give 3-chloro-1-(1-methyl-1H-benzimidazol-2-yl)-(4'-substituted)-phenylazetidin-2-one 5a-5g. A total of 14 compounds were synthesized and characterized by IR, 1H NMR, 13C NMR and Mass spectral technique, in addition they were evaluated for anti-bacterial and cytotoxic properties. Among the chemicals tested 4a, 4b, 5a, 5b, 5g exhibited good antibacterial activity and 5f, 5g shown good cytotoxic activity in vitro. © 2011. Source

Herbal medicines are widely used from their established traditional exploit for thousands of year. A number of herbal drugsshow promising hepatoprotective activities in acute and chronic liver damage. In the present paper five plants (Madhuca longifolia, Polyalthia longifolia, Delonix regia, Albizzia lebbeck, Tribulus terristoris,) are viewed for historical, morphological, phytochemical and pharmacological aspects.The plants described contain antioxidant principles that can explain and justify their use in traditional medicine in the past. Since the evidence supporting the use of botanicals to treat chronic liver disease is insufficient and only few of them are well standardized and free of potential serious side effects, most of these medications are not recommended outside clinical trials.
