KDR kinase inhibition is considered to play an important role in regulating angiogenesis, which is vital for the survival and proliferation of tumor cells. Recently we disclosed a structure-based kinase inhibitor design strategy which led to the identification of a new class of VEGFR-2/KDR kinase inhibitors bearing heterocyclic substituted pyrazolones as the core template. Instability in a rat S9 preparation and poor iv PK profiles for most of these inhibitors necessitated exploration of new pyrazolones to identify new analogs with improved metabolic stability. Optimization of the heterocyclic moiety led to the identification of the thiadiazole series of pyrazolones (D) as potent VEGFR-2/KDR kinase inhibitors. SAR modifications, kinase selectivity profiling, and structural elements for improved PK properties were explored. Oral bioavailability up to 29% was achieved in the rat. Modeling results based on the Glide XP docking approach supported our postulation regarding the interaction of the lactam segment of the pyrazolones with the hinge region of the KDR kinase.

A racemic synthesis of mersicarpine (1) was achieved by the Mizoroki-Heck reaction and a DIBALH-mediated reductive ring-expansion reaction. Based on a first-generation synthesis, a second-generation enantiocontrolled total synthesis of (-)-mersicarpine (1) was achieved by an 8-pot/11-step sequence in 21 % overall yield from commercially available 2-ethylcyclohexanone. Subjection of a ketoester, which was prepared by an asymmetric Michael addition (according to the protocol by d’Angelo and Desmaele), and phenylhydrazine to modified Fischer indole conditions provided a six-membered tricyclic indole. Benzylic oxidation and subsequent oxime formation provided a ketoxime, which was treated with diisobutylaluminum hydride (DIBALH) to construct the characteristic azepinoindole skeleton in good yield. In the DIBALH-mediated reductive ring-expansion reaction, gradually increasing the reaction temperature and in situ-protection of the nitrogen in an oxygen-sensitive azepinoindole with a benzyloxycarbonyl (Cbz) group were crucial for the high-yielding process. With these methodologies, the short-step and efficient synthesis of (-)-mersicarpine was accomplished. Several synthetic efforts are also described. Copyright

In a Review，once mentioned of 272-49-1

C-N bond formation reactions are the most important transformations in (bio)organic chemistry because of the widespread occurrence of amines in pharmaceuticals, natural products, and biologically active compounds. The Hofmann rearrangement is a well-known method used for the preparation of primary amines from amides. But, the traditional version of the Hofmann rearrangement often gave relatively poor yields due to over-oxidation or due to the poor solubility of some amides in aqueous base, and created an enormous amount of waste products. Developments over the last two decades, in particular, have focused on refining both of these factors affecting the reaction. This review covers both the description of recent advances (2000-2019) in the Hofmann rearrangements and its applications in the synthesis of heterocycles, natural products and complex molecules of biological interest. It is revealed that organo-catalytic systems especially hypervalent iodine-based catalysts have been developed for the green and environmentally friendly conversion of carboxamides to primary amines and carbamates.

The reversible photochemical ion chelation of the newly synthesised substituted N,N?-bis(spiro[1-benzopyran-2,2?-indolyl])diazacrown systems 15a-c and the subsequent molecular electronic control of this process using appropriately placed substituent groups on the spiro-benzopyran skeleton is reported. The principle of molecular electronic control of ion chelation is demonstrated by comparing the behaviour of the newly synthesised nitro-substituted and pyrido-annulated spiro-benzopyran system 9b with that of the unsubstituted compound 9a. Electronic substituent control over ion chelation is then exemplified for the new N,N?-bis(5?-nitrospiro[1- benzopyran-2,2?-indolyl])diazacrown system 15c and further exemplified for the corresponding 5?-trifluoromethyl derivative 15b, which contains the photochemically more robust trifluoromethyl group. The crown system 15a, unsubstituted in the spiro-indole moiety, is also reported. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.

The beta-catenin/T-cell factor (Tcf) protein-protein interaction (PPI) plays a critical role in the beta-catenin signaling pathway which is hyperactivated in many cancers and fibroses. Based on compound 1, which was designed to target the Tcf4 G13ANDE17 binding site of beta-catenin, extensive structure-activity relationship studies have been conducted. As a result, compounds 53 and 57 were found to disrupt the beta-catenin/Tcf PPI with the Ki values of 0.64 and 0.44 muM, respectively, and exhibit good selectivity for beta-catenin/Tcf over beta-catenin/E-cadherin and beta-catenin/adenomatous polyposis coli (APC) PPIs. The 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) cell viability assays revealed that 56, the ethyl ester of 53, was more potent than 53 in inhibiting viability of most of the Wnt/beta-catenin hyperactive cancer cells. Further cell-based studies indicated that 56 disrupted the beta-catenin/Tcf PPI without affecting the beta-catenin/E-cadherin and beta-catenin/APC PPIs, suppressed transactivation of Wnt/beta-catenin signaling in dose-dependent manners, and inhibited migration and invasiveness of Wnt/beta-catenin-dependent cancer cells.

The SAR of a series of 1-amino-3-(1H-indol-1-yl)-3-phenylpropan-2-ols as monoamine reuptake inhibitors, with a goal to improve both potency toward inhibiting the norepinephrine transporter and selectivity over the serotonin transporter, is reported. The effect of specific substitution on both the 3-phenyl group and the indole moiety were explored. This study led to the discovery of compound 20 which inhibited the norepinephrine transporter with an IC50 value of 4 nM while exhibiting 86-fold selectivity over the serotonin transporter.
