A lanostane aldehyde from Momordica charantia

A new lanostane aldehyde, charantal (1), was isolated from the ethanolic leaf extract of Momordica charantia together with the known compound, 2,4-bis(2-phenylpropan-2-yl)phenol (2). The structure of compound 1 was elucidated by extensive 1D and 2D NMR and MS experiments. Compound 2 displayed a moderately strong antitubercular activity against Mycobacterium tuberculosis H37Rv (MIC = 14 mug/mL) according to the MABA susceptibility assay.

Rh(iii)-Catalyzed tandem indole C4-arylamination/annulation with anthranils: Access to indoloquinolines and their application in photophysical studies

An efficient Rh(iii)-catalyzed straightforward strategy was developed for the tandem C4 arylamination/annulation of indole derivatives with anthranil to provide indoloquinoline moieties. This method is simple and regioselective with a wide scope and functional group tolerance. Mechanistic studies revealed the important role of the newly installed azacycle in the conversion of O-protected aldoximes to their cyano derivatives. Studies were carried out to explore the promising photophysical properties of the obtained indoloquinoline derivatives.

Optimization of chemical functionalities of indole-2-carboxamides to improve allosteric parameters for the cannabinoid receptor 1 (CB1)

5-Chloro-3-ethyl-N-(4-(piperidin-1-yl)phenethyl)-1H-indole-2-carboxamide (1; ORG27569) is a prototypical allosteric modulator for the cannabinoid type 1 receptor (CB1). Here, we reveal key structural requirements of indole-2-carboxamides for allosteric modulation of CB1: a critical chain length at the C3-position, an electron withdrawing group at the C5-position, the length of the linker between the amide bond and the phenyl ring B, and the amino substituent on the phenyl ring B these significantly impact the binding affinity (KB) and the binding cooperativity (alpha). A potent CB1 allosteric modulator 5-chloro-N-(4-(dimethylamino)phenethyl)-3-propyl-1H-indole- 2-carboxamide (12d) was identified. It exhibited a KB of 259.3 nM with a strikingly high binding alpha of 24.5. We also identified 5-chloro-N-(4-(dimethylamino)phenethyl)-3-hexyl-1H-indole-2-carboxamide (12f) with a KB of 89.1 nM, which is among the lowest KB values obtained for any allosteric modulator of CB1 these positive allosteric modulators of orthosteric agonist binding nonetheless antagonized the agonist-induced G-protein coupling to the CB1 receptor, yet induced beta-arrestin mediated ERK1/2 phosphorylation.

Dynamic Carbon Isotope Exchange of Pharmaceuticals with Labeled CO2

A copper-catalyzed procedure enabling dynamic carbon isotope exchange is described. Utilizing the universal precursor [14C]CO2, this protocol allows to insert, in one single step, the desired carbon tag into carboxylic acids with no need of structural modifications. Reducing synthetic costs and limiting the generation of radioactive waste, this procedure will facilitate the access to carboxylic acids containing drugs and accelerate early 14C-based ADME studies supporting drug development.

Chiral Imidodiphosphoric Acid-Catalyzed Highly Diastereo- and Enantioselective Synthesis of Poly-Substituted 3,4-Dihydro-2 H-pyrans: [4 + 2] Cycloadditions of beta,gamma-Unsaturated alpha-Ketoesters and 3-Vinylindoles

Imidodiphosphoric acids were employed to catalyze inverse-electron-demand hetero-Diels-Alder reaction of beta,gamma-unsaturated alpha-ketoesters and 3-vinylindoles. A series of optically active 3,4-dihydro-2H-pyran derivatives with three contiguous stereogenic centers was synthesized in excellent yields (70-99%), diastereoselectivities (>20:1), and enantioselectivities (73-99%). The resulting indole containing 3,4-dihydro-2H-pyran could be converted to tetrahydropyran derivatives, which appear in several biological active compounds by simple hydrogenation reduction.

A novel near-infrared ?turn-on? fluorescent probe for selective detection of Fe3+ and its application in vitro imaging

A novel near-infrared fluorescent probe RHCC was devised and synthesized. It exhibits high specificity to Fe3+ compared to other metals in aqueous solutions. The detection limit of RHCC was 1.2 ¡Á 10?7 M and the complexation stability constant was 5.807 ¡Á 104 M?1. The binding ratio of RHCC and Fe3+ was 1:1 which was measured through MS, FTIR and Job’s plot. The energy gap between HOMO and LUMO of RHCC was 3.22 eV, while RHCC-Fe3+ complex was 0.95 eV. This result means the binding of probe RHCC and Fe3+ lowers the RHCC-Fe3+ complex’s energy gap and makes it more stable. What’s more, in living cells and zebrafishes studies, probe RHCC was no significant cytotoxic effect, indicating it could monitor Fe3+ in biological system.
