Synthesis of Some Quinazoline Derivatives Functionalized with3-Heterocycles Side Chain
Utilization of benzoxazinone for synthesis quinazolinone derivatives with 3-heterocycle side chain. treatment of benzoxazinon 1 with cyano acetohydrazide or thionocarbohydrazide gave the quinazolinone derivatives 2 or 12. quinazolinone 2 has been utilized as synthon for new pyridinone, oxazet, thiazole, thiazolidinone and quinazolinone derivatives. Thiosemicarbazide and thiosemicarbazone deriv...
متن کاملGlutamine and Asparagine Side Chain Hyperconjugation-Induced Structurally Sensitive Vibrations.
We identified vibrational spectral marker bands that sensitively report on the side chain structures of glutamine (Gln) and asparagine (Asn). Density functional theory (DFT) calculations indicate that the Amide III(P) (AmIII(P)) vibrations of Gln and Asn depend cosinusoidally on their side chain OCCC dihedral angles (the χ3 and χ2 angles of Gln and Asn, respectively). We use UV resonance Raman ...
متن کاملSide chain conjugation prevents bacterial 7-dehydroxylation of bile acids.
The effect of side chain conjugation on 7-dehydroxylation of bile acids has been investigated. C24-bile acids and their glycine and taurine conjugates and keto bile acids were incubated with pure strains of Eubacterium sp. VPI 12708. Bile acids of the 5 alpha- or 5 beta-series with a free terminal carboxyl group and a 3 alpha, 7 alpha-dihydroxy system were very effectively 7 alpha-dehydroxylate...
متن کاملIi. Renal Function Influenced by Proteose Intoxication
The injection of the toxic proteose obtained from the contents of the obstructed small intestine causes a definite impairment of the eliminative function of the kidneys as shown by a decreased capacity to excrete urea, sodium chloride, and phenolsulfonephthalein. This involvement of the renal function is similar to that shown by the preceding report (1) to accompany the intoxication of intestin...
متن کامل7 Types of Cooperation Episodes in Side-by-Side Programming
In side-by-side programming, two programmers (typically working on related aspects of a project) move their computers so close to one another that they can effortlessly change between working alone and working together, where working alone is the primary mode. The technique was proposed in order to obtain some of the advantages of pair programming at much lower overhead. As a first step towards...
