PROPERTIES AKD DISTRIBUTIOiC’ OF VITAMIN B12r*
The existence of a new form of vitamin B,, in the feces of rats was first noted during a study of the effect of dietary cobalt on the growth of rats employed for vitamin Blz assay (1). When crude extracts of the feces ivere tested by the microbiological and rat assays, only a small fraction of the vitamin B,, activity measured microbiologically could be detected by the rat assay. Upon chromatog...
متن کاملSynthesis of labile methyl groups by guinea pig tissue in vitro.
The formation of the methyl groups of methionine and choline from C”-labeled formate has been demonstrated in the intact rat (1-3) and in rat liver slices (1). Du Vigneaud and his coworkers (’2) have also shown the incorporation of the carbon of formaldehyde into the methyl groups of choline. It is conceivable that in rat liver the carbon of formate or formaldehyde is first incorporated into th...
متن کاملTriphenylphosphine Catalysed Facile Multicomponent Synthesis of 2-Amino-3-Cyano-6-Methyl-4-Aryl-4H-Pyrans
Triphenyl phosphine(PPh3), an efficient and reusable catalyst, catalysed the synthesis of 2-amino-3-cyano-6-methyl-4-aryl-4H-pyran-5-ethylcarboxylate derivatives by one-pot condensation of aromatic aldehydes, malononitrile and ethyl acetoacetate in EtOH-H2O (1:1) at reflux conditions. The results show that ...
متن کاملInhibition of heme synthesis by methyl-substituted benzimidazoles in vitro.
Emerson and associates (1) noted that 2,5-dimethylbenzimidazole appeared to act as a growth depressant when fed to rats in tests of compounds for vitamin Blz-like activity. This property was not exhibited by benzimidazole or any of the other monoor dimethylbenzimidazoles studied. They remarked that 2,5-dimethylbenzimidazole might have “inhibitor activity.” 2,5-Dimethylbenzimidazole inhibited re...
متن کاملsynthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
