The Discovery of a Dual TTK Protein Kinase/CDC2-Like Kinase (CLK2) Inhibitor for the Treatment of Triple Negative Breast Cancer Initiated from a Phenotypic Screen

Triple negative breast cancer (TNBC) remains a serious unmet medical need with discouragingly high relapse rates. We report here the synthesis and structure-activity relationship (SAR) of a novel series of 2,4,5-trisubstituted-7H-pyrrolo[2,3-d]pyrimidines with potent activity against TNBC tumor cell lines. These compounds were discovered from a TNBC phenotypic screen and possess a unique dual inhibition profile targeting TTK (mitotic exit) and CLK2 (mRNA splicing). Design and optimization, driven with a TNBC tumor cell assay, identified potent and selective compounds with favorable in vitro and in vivo activity profiles and good iv PK properties. This cell-based driven SAR produced compounds with strong single agent in vivo efficacy in multiple TNBC xenograft models without significant body weight loss. These data supported the nomination of CC-671 into IND-enabling studies as a single agent TNBC therapy.

SYNTHESIS OF INSECT ATTRACTANTS (SEX ATTRACTANTS). VIII. STEREOSELECTIVE SYNTHESIS OF FOUR ISOMERS OF 5,7-DODECADIEN-1-OL AND THEIR ACETATES AND ALDEHYDES, COMPONENTS OF THE SEX PHEROMONES OF INSECTS OF THE Lasiocampidae (Lepidoptera) FAMILY

A new method is proposed for the stereoselective synthesis of four stereoisomers of 5,7-dodecadien-1-ol and their acetates and aldehydes on the basis of the Wittig reaction. 7-(2-Tetrahydropyranyloxy)-2-heptyn-1-ol was obtained by the alkylation of 2-propyn-1-ol with 2-(4-bromobutoxy)tetrahydropyran.By hydrogenation in the presence of colloidal nickel catalyst or by reduction with lithium aluminum hydride it was converted into the Z and E isomers respectively of 7-(2-tetrahydropyranyloxy)-2-hepten-1-ol.Oxidation of the alcohol group in the above-mentioned hydroxy acetals led to the corres ponding aldehydes, which then entered into the Wittig reaction with pentylidenetriphenylphosphorane under the conditions for the formation of a double bond with a specific configuration of the isomers (Z and E).Subsequent removal of the tetrahydropyranyl protection of the alkyl group in the Wittig reaction products gave 5,7-dodecadien-1-ols, which were converted into the corresponding acetates of the aldehydes by acetylation of oxidation.The products are components of the sex pheromones of insects of the Lasiocampidae family.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 2-(4-Bromobutoxy)tetrahydro-2H-pyran, you can also check out more blogs about31608-22-7

Effect of Treatment Methods on Chitin Structure and Its Transformation into Nitrogen-Containing Chemicals

Chitin treatment using different methods, including ball mill grinding, steam explosion, alkaline treatment, phosphoric acid, and ionic liquid (IL) dissolution/reprecipitation have been systematically investigated. The chitin structures were thoroughly investigated by using a series of analytical techniques, and the reactivity after each treatment was evaluated in dehydration and liquefaction reactions. The parallel studies enable direct comparisons of these methods and help to establish the structure-activity correlations. Ball mill grinding in dry mode was the most effective method, with the crystal size and the hydrogen-bond network being the two crucial factors in enhancing the reactivity. Remarkably, the yield of 3-acetamido-5-acetylfuran (3A5AF) from chitin dehydration increased to the highest amount (28.5%) after ball mill grinding (the previous record yield was 7.5% for untreated chitin).
