The invention relates to novel nitrogen- and sulfur-containing heterocyclic compounds of the formula (I), acid addition salts thereof, pharmaceutical compositions containing them and a process for their preparation. In the formula (I) STR1 Ar stands for an optionally mono- or polysubstituted aryl or heteroaryl group; R1 means a carbonyl or (C2-6 alkenyl)carbonyl group; R2 stands for hydrogen C1-6 alkyl, phenyl or phenyl (C1-4 alkyl) group; R3 means hydrogen or (C1-6 alkoxy)carbonyl group; R4 and R5 stand, independently from each other, for hydrogen or C1-6 alkyl group; R6 ogen, C1-6 alkyl group or halophenyl group; m is 0 or 1; and n is 1 or 2, with the proviso that R2 means hydrogen when m is 0. The compounds of formula (I) show a significant cerebral antihypoxic action and thus, they can be used for the treatment of diseases caused by hypoxic brain damages such as e.g. the senile dementia, Alzheimer’s disease or disturbances of the cognitive function.

Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. In a patent, 2682-49-7, name is Thiazolidin-2-one, introducing its new discovery. SDS of cas: 2682-49-7

alpha-Glucosidase enzyme inhibition is an effective therapeutic decorum in the treatment of type 2 diabetes mellitus. Since 1990, three alpha-glucosidase inhibitors are known to exist clinically, Acarbose, Voglibose and Miglitol. Side effects and long synthetic routes to access them forced the researchers to move their focus to discover simple and small heterocyclic motifs that work as promising alpha-glucosidase inhibitors and may eventually lead to the management of postprandial hyperglycemic condition in T2DM. In this regards, this review deals with recently discovered heterocyclic molecules that have been evaluated to exhibit inhibition of alpha-glucosidase enzyme.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2682-49-7 is helpful to your research. SDS of cas: 2682-49-7

Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. In a patent, 76186-04-4, name is (S)-4-Isopropylthiazolidine-2-thione, introducing its new discovery. Synthetic Route of 76186-04-4

A two-stage “tandem strategy” for the synthesis of benzofused nitrogen heterocycles is described that is particularly useful for the construction of systems with a high level of substitution on the benzenoid ring. The first stage in the strategy involves a benzannulation based on the reaction of cyclobutenones with ynamides. This cascade process proceeds via a sequence of four pericyclic reactions and furnishes a multiply substituted aniline derivative which can bear a variety of functionalized substituents at the position ortho to the nitrogen. In the second stage of the tandem strategy, ringclosing metathesis generates the nitrogen heterocyclic ring. This two-step sequence provides efficient access to highly substituted dihydroquinolines, benzazepines, benzazocines, and related benzofused nitrogen heterocyclic systems. The application of this chemistry in a concise formal total synthesis of the anticancer agents (?)-FR900482 and (?)-FR66979 is described. 2011 American Chemical Society.
