Visible-Light-Mediated Metal-Free Difunctionalization of Alkenes with CO2 and Silanes or C(sp3)?H Alkanes

Catalytic alkene difunctionalization via Si?H and C?H activations represents an ideal atom- and step-economic pathway for quick assembly of molecular complexity. We herein developed a visible-light-promoted metal-free difunctionalization of alkenes using abundant CO2 and readily available Si?H and C(sp3)?H bonds as feedstocks. Through the merger of photoredox and hydrogen-atom-transfer catalysis, a variety of value-added compounds, such as beta-silacarboxylic acids and acids bearing a gamma-heteroatom (e.g., N, O, S) could be directly accessed from simple alkenes in a redox-neutral fashion.

Mechanism of vascular relaxation by cholinomimetic drugs with special reference to pilocarpine and arecoline

The muscarinic receptor-mediated and non-muscarinic vascular effects of cholinomimetic drugs used in glaucoma were quantified. On the isolated rat aorta, the vascular tone induced by phenylephrine is functionally antagonized by cholinomimetic drugs. Based on EC50, the relative order of potency for the endothelium-dependent vascular relaxation was acetylcholine (0.05 muM) 1 > (¡À)-methacholine (0.35 muM) 1/7 > carbachol (0.63 muM) 1/12 > (¡À)-aceclidine (1.26 muM) 1/25. The maximal effects of the four agonists varied between 82-87%. The muscarinic vascular relaxation of 0.03 muM to 100 muM pilocarpine was less than 15%. At high concentrations, pilocarpine had 1/20,000 the vascular activity of acetylcholine. Physostigmine failed to potentiate the vascular relaxation of exogenous acetylcholine, indicating the absence of acetylcholine esterase in the tissue. Arecoline, with an EC50 of 7.76 muM, was partly sensitive to the removal of the endothelium. Atropine treatment did not block the vascular effect of high concentrations of pilocarpine. Atropine, as expected, blocked the vascular effects of carbachol with KB = 3.2 nM. Pilocarpine produces vascular relaxation by its competition with spasmogens like phenylephrine, oxymetazoline, vasopressin or latanoprost. Arecoline also shares these properties with pilocarpine in the blood vessel. The molecular mechanism of the vascular effects as well as ocular clinical implications of cholinomimetic drugs is discussed.

Muscarinic contraction in isolated guinea-pig trachea and antagonism by noradrenaline

In contrast to other muscarinic agonists, WAL 2014 FU does not induce bronchospasm in laboratory animals. The present investigation was intended to test the hypothesis that this is due to a particular susceptibility of the drug’s effect to antagonism by catecholamines, as a result of partial M3- agonism. The tonic activity of the muscarinic agonists, aceclidine, arecoline, carbachol, McN-A-343, RS 86, thiopilocarpine and WAL 2014 FU, was tested in groups of isolated tracheal muscle of the guinea-pig. Susceptibility to functional antagonism by beta-adrenoceptor stimulation was measured by the displacement of the concentration-force curves by 3 muM noradrenaline. Evaluation of the concentration-force relationship revealed differences in potency and intrinsic activity (carbachol=100%) ranging from 114% for arecoline to 36% for thiopilocarpine (WAL 2014 FU=63%). The catecholamine increased the concentration of agonist which induced 5% of the maximum effect achievable (EC05) values fivefold (carbachol) to more than 4,680 fold (thiopilocarpine) (WAL 2014 FU: 2,860 fold). Regression analysis between the intrinsic activity of the seven compounds and the antagonistic effect of noradrenaline revealed a significant correlation (Spearman correlation coefficient (r(s)) =-0.79; p=0,036). Inhibition of the effects of endogenous catecholamines by beta-adrenolysis with 50 muM toliprolol increased the maximal contraction induced by 1 mM WAL 2014 FU, but did not affect maximal contraction induced by 30 muM arecoline. Pretreatment with 0.3-1.0 mM dibutyrylcyclic adenosine monophosphate (DBcAMP) shifted the concentration- response curves of arecoline, WAL 2014 FU and thiopilocarpine in a similar manner to noradrenaline. The results exclude an important contribution of adenylate cyclase-coupled M2-receptors to the susceptibility of tracheal contraction by muscarinic agonists to functional antagonism by noradrenaline, but emphasize the importance of intrinsic activity at the M3-receptors. The pronounced susceptibility of WAL 2014 FU-induced contraction to functional antagonism by beta-adrenoceptor activation provides an explanation for the failure of the drug to induce bronchospasm in vivo.

APR-246/PRIMA-1MET inhibits thioredoxin reductase 1 and converts the enzyme to a dedicated NADPH oxidase

The low-molecular-weight compound APR-246 (PRIMA-1MET) restores wild-type conformation and function to mutant p53, and triggers apoptosis in tumor cells. We show here that APR-246 also targets the selenoprotein thioredoxin reductase 1 (TrxR1), a key regulator of cellular redox balance. APR-246 inhibited both recombinant TrxR1 in vitro and TrxR1 in cells. A Sec-to-Cys mutant of TrxR1 was not inhibited by APR-246, suggesting targeting of the selenocysteine residue in wild-type TrxR1. Preheated APR-246 and its conversion product methylene quinuclidinone (MQ) were much more efficient TrxR1 inhibitors than APR-246 itself, indicating that MQ is the active compound responsible for TrxR1 enzyme inhibition. TrxR1 inhibited by MQ was still functional as a pro-oxidant NADPH oxidase. Knockdown of TrxR1 caused a partial and reproducible attenuation of APR-246- induced tumor cell death independently of p53 status. Cellular TrxR1 activity was also inhibited by APR-246 irrespective of p53 status. We show that APR-246 can directly affect cellular redox status via targeting of TrxR1. Our findings provide an explanation for the previously observed effects of APR-246 on tumor cells lacking mutant p53.
