Discovery and structure-activity relationship of novel 2,3- dihydrobenzofuran-7-carboxamide and 2,3-dihydrobenzofuran-3(2 h)-one-7-carboxamide derivatives as poly(ADP-ribose)polymerase-1 Inhibitors

Novel substituted 2,3-dihydrobenzofuran-7-carboxamide (DHBF-7-carboxamide) and 2,3-dihydrobenzofuran-3(2H)-one-7-carboxamide (DHBF-3-one-7-carboxamide) derivatives were synthesized and evaluated as inhibitors of poly(ADP-ribose) polymerase-1 (PARP-1). A structure-based design strategy resulted in lead compound 3 (DHBF-7-carboxamide; IC50 = 9.45 muM). To facilitate synthetically feasible derivatives, an alternative core was designed, DHBF-3-one-7-carboxamide (36, IC50 = 16.2 muM). The electrophilic 2-position of this scaffold was accessible for extended modifications. Substituted benzylidene derivatives at the 2-position were found to be the most potent, with 3?,4?-dihydroxybenzylidene 58 (IC50 = 0.531 muM) showing a 30-fold improvement in potency. Various heterocycles attached at the 4?-hydroxyl/4?-amino of the benzylidene moiety resulted in significant improvement in inhibition of PARP-1 activity (e.g., compounds 66-68, 70, 72, and 73; IC50 values from 0.718 to 0.079 muM). Compound 66 showed selective cytotoxicity in BRCA2-deficient DT40 cells. Crystal structures of three inhibitors (compounds (-)-13c, 59, and 65) bound to a multidomain PARP-1 structure were obtained, providing insights into further development of these inhibitors.

Copper-Catalyzed Tandem Hydrocupration and Diastereo- and Enantioselective Borylalkyl Addition to Aldehydes

We report the copper-catalyzed stereoselective addition of in situ generated chiral boron-alpha-alkyl intermediates to various aldehydes including alpha,beta-unsaturated aldehydes under mild conditions. This tandem and multicomponent method facilitated the synthesis of enantiomerically enriched 1,2-hydroxyboronates bearing contiguous stereocenters in good yield with high diastereo- and enantioselectivity up to a ratio greater than 98:2. In particular, alpha,beta-unsaturated aldehydes were successfully used as electrophiles in Cu?H catalysis through 1,2-addition without significant reduction. The resulting 1,2-hydroxyboronates were used in various transformations.

N-(4-(4-(2,3-dichloro- or 2-methoxyphenyl)piperazin-1-yl)butyl) heterobiarylcarboxamides with functionalized linking chains as high affinity and enantioselective D3 receptor antagonists

In the present report, the D3 receptor pharmacophore is modified in the 2,3-diCl- and 2-OCH3-phenyl-piperazine class of compounds with the goal to improve D3 receptor affinity and selectivity. This extension of structure-activity relationships (SAR) has resulted in the identification of the first enantioselective D3 antagonists (R- and S-22) to be reported, wherein enantioselectivity is more pronounced at D3 than at D2, and that a binding region on the second extracellular loop (E2) may play a role in both enantioselectivity and D3 receptor selectivity. Moreover, we have discovered some of the most D3-selective compounds reported to date that show high affinity (Ki) 1 nM) for D3 and ?400-fold selectivity over the D2 receptor subtype. Several of these analogues showed exquisite selectivity for D3 receptors over >60 other receptors, further underscoring their value as in vivo research tools. These lead compounds also have appropriate physical characteristics for in vivo exploration and therefore will be useful in determining how intrinsic activity at D3 receptors tested in vitro is related to behaviors in animal models of addiction and other neuropsychiatric disorders.

High-resolution spectroscopic study of matrix-isolated reactive intermediates: Vibrational assignments for 3-fluoro-o-benzyne and perfluoro-o-benzyne

A novel “site decompression technique” that takes advantage of specific pressure relaxation effects in cryogenic noble gas matrices was applied in a spectroscopic investigation of the two title compounds, resulting in virtually background-free, complete, high-resolution IR spectra with line widths of ca. 0.1 cm-1. The compounds were prepared photochemically in Ar and Ne matrices and, together with the related intermediates, fluorinated benzocyclopropenone and cyclopentadienylideneketene, characterized by IR and UV-visible absorption spectroscopy. Weak IR absorption bands observed at 1878 cm-1 for perfluoro-o-benzyne and at 1866 cm-1 for 3-fluoro-o-benzyne were assigned to CC triple bond stretching vibrations, corresponding to the transition at 1846 cm-1 in the parent o-benzyne. The application of polarization spectroscopy on photooriented samples led to the determination of transition moment directions for most of the observed vibrational transitions. Absolute IR absorption intensities were also obtained. The assignments of the observed transitions were supported by the results of B3LYP/cc-pVDZ quantum chemical calculations.

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 4-Fluoroisobenzofuran-1,3-dione, you can also check out more blogs about652-39-1

Design, synthesis and biological evaluation of new embelin derivatives as CK2 inhibitors

A new series of furan embelin derivatives was synthesized and characterized as ATP-competitive CK2 inhibitors. The new compounds were efficiently synthesized using a multicomponent approach from embelin (1), aldehydes and isonitriles through a Knoevenagel condensation/Michael addition/heterocyclization. Several compounds with inhibitory activities in the low micromolar or even submicromolar were identified. The most active derivative was compound 4l (2-(tert-butylamino)-3-(furan-3-yl)-5-hydroxy-6-undecylbenzofuran-4,7-dione) with an IC50 value of 0.63 muM. It turned out to be an ATP competitive CK2 inhibitor with a Ki value determined to be 0.48 muM. Docking studies allowed the identification of key ligand-CK2 interactions, which could help to further optimize this family of compounds as CK2 inhibitors.
