Doebelin, Christelle’s team published research in Medicinal Chemistry (Sharjah, United Arab Emirates) in 15 | CAS: 10543-42-7

Medicinal Chemistry (Sharjah, United Arab Emirates) published new progress about 10543-42-7. 10543-42-7 belongs to chlorides-buliding-blocks, auxiliary class Other Aromatic Heterocyclic,Chloride,Sulfonyl chlorides,Ester, name is Coumarin-6-sulfonyl chloride, and the molecular formula is C9H5ClO4S, Quality Control of 10543-42-7.

Doebelin, Christelle published the artcileDiscovery and Optimization of a Series of Sulfonamide Inverse Agonists for the Retinoic Acid Receptor-Related Orphan Receptor-a, Quality Control of 10543-42-7, the publication is Medicinal Chemistry (Sharjah, United Arab Emirates) (2019), 15(6), 676-684, database is CAplus and MEDLINE.

Background: Despite a massive industry endeavor to develop RORalpha-modulators for autoimmune disorders, there has been no indication of efforts to target the close family member RORa for similar indications. This may be due to the misconception that RORa is redundant to RORalpha, or the inherent difficulty in cultivating tractable starting points for RORa. RORa-selective modulators would be useful tools to interrogate the biol. of this understudied orphan nuclear receptor. Objective: The goal of this research effort was to identify and optimize synthetic ligands for RORa starting from the known LXR agonist T0901317. Methods: Fourty-five analogs of the sulfonamide lead (1) were synthesized and evaluated for their ability to suppress the transcriptional activity of RORa, RORalpha, and LXRa in cell-based assays. Analogs were characterized by 1H-NMR, 13C-NMR, and LC-MS anal. The pharmacokinetic profile of the most selective RORa inverse agonist was evaluated in rats with i.p. (i.p.) and per oral (p.o.)dosing. Results: Structure-activity relationship studies led to potent dual RORa/RORalpha inverse agonists as well as RORa-selective inverse agonists (20, 28). LXR activity could be reduced by removing the sulfonamide nitrogen substituent. Attempts to improve the potency of these selective leads by varying substitution patterns throughout the mol. proved challenging.

All of the reactions have been done under green conditions without using any hazardous solvent. Also, the anti-bacterial properties of the synthesized sulfonamides I, II, III and IV were investigated using two strains of Staphylococcus (gram-pos.) and Escherichia coli (gram-neg.) bacteria.

A chiral aryl iodide e.g., I promotes the enantioselective oxidative cyclization of 1-naphtholic sulfonamides II (R1 = H, Cl, Ph, 3,5-di(trifluoromethyl)phenyl, etc.; R2 = Me, Bn, 4-methylphenyl, 4-nitrophenyl) and III (R = H, OMe), albeit in moderate ee and low yield. The products (R)/(S)-IV and V tend to crystallize as conglomerates. Recrystallization thus increases their ee to > 99% ee. This highly enantioenriched material provides seed crystals for the resolution of racemate (±)-1′-(methylsulfonyl)-1H-spiro[naphthalene-2,2′-pyrrolidine]-1-one (prepared in high yield by oxidative cyclization with (diacetoxyiodo)benzene in trifluoroacetic acid) by coupled preferential crystallization This enables the production of significant quantities of highly enantioenriched products, despite the low efficiency of the enantioselective reaction.

Jansen, Koen published the artcileExtended Structure-Activity Relationship and Pharmacokinetic Investigation of (4-Quinolinoyl)glycyl-2-cyanopyrrolidine Inhibitors of Fibroblast Activation Protein (FAP), Recommanded Product: 2-Chloroisonicotinic acid, the publication is Journal of Medicinal Chemistry (2014), 57(7), 3053-3074, database is CAplus and MEDLINE.

Fibroblast activation protein (FAP) is a serine protease related to dipeptidyl peptidase IV (DPPIV). It has been convincingly linked to multiple disease states involving remodeling of the extracellular matrix. FAP inhibition is investigated as a therapeutic option for several of these diseases, with most attention so far devoted to oncol. applications. The authors previously discovered the N-4-quinolinoyl-Gly-(2S)-cyanoPro scaffold as a possible entry to highly potent and selective FAP inhibitors. In the present study, the authors explore in detail the structure-activity relationship around this core scaffold. The authors report extensively optimized compounds that display low nanomolar inhibitory potency and high selectivity against the related dipeptidyl peptidases (DPPs) DPPIV, DPP9, DPPII, and prolyl oligopeptidase (PREP). The log D values, plasma stabilities, and microsomal stabilities of selected compounds were found to be highly satisfactory. Pharmacokinetic evaluation in mice of selected inhibitors demonstrated high oral bioavailability, plasma half-life, and the potential to selectively and completely inhibit FAP in vivo.
