5-Alkyl-1,2,3,4-tetrahydroquinolines, new membrane-interacting lipophilic metabolites produced by combined culture of streptomyces nigrescens and tsukamurella pulmonis

Eight novel 5-alkyl-1,2,3,4-tetrahydroquinolines (5aTHQs) bearing different side chains have been isolated from a combined culture of Streptomyces nigrescens HEK616 and Tsukamurella pulmonis TP-B0596. The chemical structures including the absolute configuration were elucidated by spectroscopic analysis and total synthesis. 5aTHQs inhibited the growth of wild-type fission yeast while only weakly inhibiting the growth of several mutant strains synthesizing premature ergosterol. These results demonstrate that 5aTHQs are novel antifungals that may target cell membranes.

PROTEIN TYROSINE PHOSPHATASE INHIBITORS AND METHODS OF USE THEREOF

Provided herein are compounds, compositions, and methods useful for inhibiting protein tyrosine phosphatase, e.g., protein tyrosine phosphatase non-receptor type 2 (PTPN2) and/or protein tyrosine phosphatase non-receptor type 1 (PTPN1), and for treating related diseases, disorders and conditions favorably responsive to PTPN 1 or PTPN2 inhibitor treatment, e.g., a cancer or a metabolic disease.

Pheromone synthesis. Part 259: Synthesis of seven methyl-branched hydrocarbons as the pheromone candidates for female Korean apricot wasp, Eurytoma maslovskii

Seven new methyl-branched hydrocarbons were synthesized, which were the pheromone candidates of the female Korean apricot wasp (Eurytoma maslovskii). They are (Z)-15-methyl-7-nonacosene (1), (Z)-17-methyl-7-hentriacontene (2), 3,7-dimethylheptacosane (3), 8,12-dimethyltriacontane (4), 8,18-dimethyltriacontane (5), 3,7,11-trimethylnonacosane (6), and 3,7,17-trimethylnonacosane (7). All of them were synthesized as stereoisomeric mixtures, employing short and simple routes. Hydrocarbon 7 was synthesized via 4,8-dimethyldecanal (71, tribolure), the red flour beetle pheromone. The hydrocarbons 1,2,3 and 6 were identified by GC–MS analysis as the components (with unknown stereochemistry) of the female-specific secretion of E. maslovskii.

Cu-catalyzed arylcarbocyclization of alkynes with diaryliodonium salts through C-c bond formation on inert C(sp3)-H bond

Copper-catalyzed arylcarbocyclization reaction of alkynes was realized with diaryliodonium salts through C-C bond formation on an inert C(sp3)-H bond. This method provides an efficient cyclization of alkyl alkynes to generate carbocycles with good step-economy. Theoretical study revealed an interesting Cu-catalyzed concerted pathway of the C-C bond formation.
