Discovery of a selective small-molecule melanocortin-4 receptor agonist with efficacy in a pilot study of sexual dysfunction in humans

The relevance of the melanocortin system to sexual activity is well established, and nonselective peptide agonists of the melanocortin receptors have shown evidence of efficacy in human sexual dysfunction. The role of the MC4 receptor subtype has received particular scrutiny, but the sufficiency of its selective activation in potentiating sexual response has remained uncertain owing to conflicting data from studies in preclinical species. We describe here the discovery of a novel series of small-molecule MC4 receptor agonists derived from library hit 2. The addition of methyl substituents at C3 and C5 of the 4-phenylpiperidin-4-ol ring was found to be markedly potency-enhancing, enabling the combination of low nanomolar potencies with full rule-of-five compliance. In general, the series shows only micromolar activity at other melanocortin receptors. Our preferred compound 40a provided significant systemic exposure in humans on both sublingual and oral administration and was safe and well tolerated up to the maximum tested dose. In a pilot clinical study of male erectile dysfunction, the highest dose of 40a tested (200 mg) provided a similar level of efficacy to sildenafil.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. COA of Formula: C4H3ClN2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1120-95-2, in my other articles.

Triarylamine-based hydrido-carboxylate rhenium(i) complexes as photosensitizers for dye-sensitized solar cells

Two new dyes based on a dinuclear rhenium complex and (E)-3-(5-(4-(bis(2?,4?-dibutoxy-[1,1?-biphenyl]-4-yl)amino)phenyl)thiophen-2-yl)-2-cyanoacrylic acid (namely D35) have been investigated as sensitizers for dye sensitized solar cells (DSSCs). Two different pyridazine ligands have been used, namely 4-pyridazine-carboxylic acid for dye 2 ([Re2(mu-H)(-D35)(CO)6(mu-pyridazine-4-COOH)]) and 4-pyridazinyl-butanoic acid for dye 3 ([Re2(mu-H)(-D35)(CO)6(mu-pyridazine-4-C3H6-COOH)]). The performances of these new dyes have been compared with those of the dye containing the bare 4-diphenylaminobenzoic acid, namely TPA, as the ancillary ligand (dye 1). Compared to dye 1, dyes 2 and 3 show an impressive tenfold increase in the absorption intensity in the range of 487-493 nm on TiO2 films, with great improvement of the light harvesting. Cyclic voltammetry experiments, performed on derivatives containing the methyl ester of the pyridazine ligands, show narrow electrochemical band gaps in the range of 1.36-1.84 eV. Solar cells with each dye have been prepared, using both iodide/triiodide and cobalt redox couples as the electrolytes, platinum or carbon as the counter electrodes, and TiO2 or SnO2 as the metal oxide photoelectrodes, respectively. The best DSSC results have been obtained using dye 3, with an overall solar-to-electric conversion efficiency of 3.5%, which greatly overcomes the previous result of 1.0% obtained for dye 1 in a not-optimized setup of the device. The performances of dye 3 are due to the presence of D35 ligand, which further suppresses the recombination of the injected electron with the electrolyte and with the oxidized state of the dye.

Antimicrobial and antioxidant evaluation of some novel synthesized pyridazinone derivatives

This study presents the synthesis and spectral analysis of novel pyridazinone derivatives. Cyclization reaction of mucochloric acid and semicarbazide hydrochloride in the presence of aqueous ethanol afforded 4,5-dichloro-2Hpyridazin- 3-one (1). Novel compounds were synthesized by treating the 4,5-dichloro-2H-pyridazin-3-one (1) with substituted aldehyde and amine derivatives. All synthesized compounds were screened for their in vitro antibacterial, antifungal activities by using the agar cup plate method. The newly synthesized compounds showed antimicrobial activity against all the strains. Compounds 3b and 3c showed very good antifungal activity against candida albicans and Aspergillus niger (minimal inhibitory concentration [MIC] = 12.5 mug/mL). Some compounds showed good activity against Gram (+ve) bacteria and Gram (-ve) bacteria. Antioxidant study was done by using DPPH fee radical scavenging activity. Antioxidant activity assay showed that compound 3b had highest scavenger activity.

Synthesis and biological evaluation of novel pyridazinone-based alpha4 integrin receptor antagonists

A novel series of pyridazinone-functionalized phenylalanine analogues was prepared and evaluated for inhibition of cellular adhesion mediated by alpha4beta1/VCAM-1 and alpha4beta 7MAdCAM-1 interactions. Concise syntheses were developed and applied for exploration of structure-activity relationships pertaining to the pyridazinone ring as well as the N-acyl phenylalanine scaffold. Potent dual antagonists of alpha4beta1 and alpha 4beta7 were generated from an amide subseries; antagonists selective for alpha4beta7 were identified from urea and carbamate-based subseries. The pharmacokinetic properties of selected members of the series have been determined in rats and demonstrate that the use of ester prodrugs and alterations to the amide linkage can lead to improved oral bioavailability in this series. An alpha4beta 7-selective member of the carbamate subseries (36c), upon oral admininstration, demonstrated in vivo efficacy in the mouse DSS colitis model.

Zinc-Catalyzed Hydroxyl-Directed Regioselective Ring Opening of Aziridines in SN2 Reaction Pathway

In this protocol, a zinc-catalyzed catalytic regioselective ring opening of electronically and sterically unbiased 2,3-aziridinyl alcohols has been accomplished. The directing effect of the hydroxyl moiety enables the selective nucleophilic attack to the C-3 position of 2,3-aziridinyl alcohols with various aromatic amines and thiophenols as nucleophiles. This operationally simple reaction provides convenient access to a variety of amino alcohols and hydroxyl sulfides in excellent regiocontrol. Moreover, simple derivatization of the ring opening product establishes a general strategy to approach internal vicinal diamines in regioselective and diastereomerically pure form.
