Antibiotic RK-682 (Antibiotic TAN 1364B, Antibiotic CI 010) Quick inquiry Where to buy Suppliers range | Antibiotic RK-682 is the calcium salt of one of a complex family of tetronic acids isolated from Streptomyces species. The formation of the salt is almost certainly an artefact of silica chromatography. RK-682 is the most extensively studied of the analogues, having been shown to inhibit protein tyrosine phosphatases and heparanase. Pharmacological studies with RK-682 demonstrated enhanced ATP-induced long-term potentiation using guinea-pig hippocampal slices. Investigation of the complex has also shown potent activity against HIV-1 protease. Group: Biochemicals. Alternative Names: Antibiotic TAN 1364B, Antibiotic CI 010. Grades: Highly Purified. CAS No. 154639-24-4(TAN1364B). Pack Sizes: 500ug. US Biological Life Sciences. | Worldwide |
Methyl (triphenylphosphoranylidene)acetate Quick inquiry Where to buy Suppliers range | Methyl (triphenylphosphoranylidene)acetate. Uses: (Methoxycarbonylmethylene) triphenylphosphorane is used in olefination reactions. Wittig reagent for the two-carbon homologation of aldehydes to α,β-unsaturated esters. it undergoes the Wittig reaction with aldehydes to give substituted methyl acrylates. used in an efficient synthesis of pyrazoles via reaction with methyl diazoacetate in the presence of triethylamine. It is used in the preparation of (triphenylphosphoranylidene)-ketene. The Wittig reaction we performed in class involved the reaction of 2-nitrobenzaldehyde (1) with methyl (triphenylphosphoranylidene) acetate (2) to produce methyl (2E)-3-(2-nitrophenyl) acrylate (3) with a triphenylphosphine oxide (4) side product, and took place in a silica gel matrix to ensure even product dispersion for chromatography.
