Quantitative structure-activity relationship analysis of inhibitors of the nicotine metabolizing CYP2A6 enzyme

The purpose of this study was to develop screening and in silico modeling methods to obtain accurate information on the active center of CYP2A6, a nicotine oxidizing enzyme. The inhibitory potencies of 26 naphthalene and 16 non-naphthalene derivatives were determined for human CYP2A6 and mouse CYP2A5 enzymes. Several comparative molecular field analysis (CoMFA) models were developed to find out what types of steric and electrostatic properties are required for potent inhibitors. The IC50 values of the tested compounds varied from 0.55 to 35 400 muM for CYP2A6 and from 1 to 1500 muM for CYP2A5. The generated CoMFA models were able to accurately predict the inhibition potencies of an external test set of chemicals. Potent and specific inhibitors of the CYP2A6 enzyme can be used in the future to increase nicotine bioavailability and thus make oral nicotine administration feasible in smoking cessation therapy.

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.category: Isoquinolines, you can also check out more blogs about1125-80-0

Design and synthesis of novel heterobiaryl amides as metabotropic glutamate receptor subtype 5 antagonists

A series of heterobiaryl amides was designed and synthesized as novel mGluR5 antagonists. The synthesis using palladium catalyzed Suzuki-Miyaura cross-coupling reactions provided an array of compounds with a range of in vitro activities. In particular, compound 9e, 4(3,5-difluorophenyl)-N-(6-methylpyridin-1-yl)picolinamide, exhibited nanomolar affinity at the mGluR5 and will serve as a template for future drug design.

PARP inhibitor development for systemic cancer targeting.

Poly(ADP-ribose) polymerase 1 (PARP-1) is a DNA-binding enzyme that is activated by DNA breaks, converting them into an intracellular signal via poly(ADP-ribosyl)ation of nuclear proteins. Negatively charged polymers of ADP-ribose (PAR) attached to PARP-1 itself and histones lead to chromatin relaxation, facilitating the access of base excision/single strand break repair proteins and activating these repair enzymes. PARP inhibitors have been developed to investigate the role of PARP-1 in cell biology and to overcome DNA repair-mediated resistance of cancer cells to cytotoxic therapy. Since the early benzamide inhibitors of the 1980s PARP inhibitors, developed through structure-activity relationships and crystal structure-based drug design, that are 1,000 x more potent have been identified. These novel PARP inhibitors have been shown to enhance the antitumour activity of temozolomide (a DNA-methylating agent), topoisomerase poisons and ionising radiation in advanced pre-clinical studies and are now under clinical evaluation. PARP inhibitors can also selectively kill cells and tumours with homozygous defects in the hereditary breast cancer genes, BRCA1 and BRCA2.

Addition reaction of 3,4-dihydroisoquinolines with gamma-hydroxy-alpha,beta-unsaturated ketones furnished a variety of diastereomerically pure oxazolo[2,3-a]tetrahydro-isoquinolines, which could be purified by either recrystallization or solvent evaporation. The reaction proceeded smoothly under “green” conditions without an additive and catalyst, giving the target molecules in good to excellent yields.

Inhibition of matrix metalloproteinase-2 by PARP inhibitors

Matrix metalloproteinase-2 (MMP-2), a ubiquitously expressed zinc-dependent endopeptidase, and poly(ADP-ribosyl) polymerase (PARP), a nuclear enzyme regulating DNA repair, are activated by nitroxidative stress associated with various pathologies. As MMP-2 plays a detrimental role in heart injuries resulting from enhanced nitroxidative stress, where PARP and MMP inhibitors are beneficial, we hypothesized that PARP inhibitors may affect MMP-2 activity. Using substrate degradation assays to determine MMP-2 activity we found that four PARP inhibitors (3-AB, PJ-34, 5-AIQ, and EB-47) inhibited 64 kDa MMP-2 in a concentration-dependent manner. The IC50 values of PJ-34 and 5-AIQ were in the high micromolar range and comparable to those of known MMP-2 inhibitors doxycycline, minocycline or o-phenanthroline, whereas those for 3-AB and EB-47 were in the millimolar range. Co-incubation of PARP inhibitors with doxycycline showed an additive inhibition of MMP-2 that was significant for 3-AB alone. These data demonstrate that the protective effects of some PARP inhibitors may include inhibition of MMP-2 activity.

A Borrowing Hydrogen Strategy for Dehydrative Coupling of Aminoisoquinolines with Benzyl Alcohols in Water

We report a borrowing hydrogen strategy for a palladium-catalyzed dehydrative coupling of aminoisoquinolines with benzylic alcohols in water. This cascade reaction using the pi-benzylpalladium system can be achieved in an atom-economic process without the need for base or other additives, furnishing the N-benzylated aminoisoquinolines in moderate to excellent yields along with water as the sole co-product. The crossover experiment using [D7]benzyl alcohol and 4-methoxybenzyl alcohol afforded H/D scrambled products. KIE experiments showed that benzylic C?H bond cleavage of benzyl alcohol was involved in the turnover limiting step (KIE = 4.4). The coupling reaction was found to be first order in benzyl alcohol with a kinetic solvent isotope effect (KSIE) of 1.6. These experimental results are consistent with a borrowing hydrogen mechanism in water. Notably, the water-soluble Pd0/TPPMS system can be applied to the more challenging catalytic benzylic amination with aminoisoquinoline nucleophiles despite the possible deactivation of PdII species.
