Pryyma, Alla published the artcileRapid, high-yielding solid-phase synthesis of cathepsin-B cleavable linkers for targeted cancer therapeutics, Recommanded Product: 2-Chlorotrityl chloride, the publication is Bioconjugate Chemistry (2020), 31(12), 2685-2690, database is CAplus and MEDLINE.

Antibody-drug conjugates (ADCs) constitute an emerging class of anticancer agents that deliver potent payloads selectively to tumors while avoiding systemic toxicity associated with conventional chemotherapeutics. Critical to ADC development is a serum-stable linker designed to decompose inside targeted cells thereby releasing the toxic payload. A protease-cleavable linker comprising a valine-citrulline (Val-Cit) motif has been successfully incorporated into three FDA-approved ADCs and is found in numerous preclin. candidates. Herein, we present a high-yielding and facile synthetic strategy for a Val-Cit linker that avoids extensive protecting group manipulation and laborious chromatog. associated with previous syntheses and provides yields that are up to 10-fold higher than by standard methods. This method is easily scalable and takes advantage of cost-effective coupling reagents and high loading 2-chlorotrityl chloride (2-CTC) resin. Modularity allows for introduction of various conjugation handles in final stages of the synthesis. Facile access to such analogs serves to expand the repertoire of available enzymically cleavable linkers for ADC generation. This methodol. empowers a robust and facile library generation and future exploration into linker analogs containing unnatural amino acids as a selectivity tuning tool.

Sureshkumar, Devarajulu published the artcileTandem aziridine ring opening-disulfide formation-reduction-Michael addition in one-pot mediated by tetrathiomolybdate, SDS of cas: 7080-50-4, the publication is Tetrahedron (2015), 71(39), 7267-7281, database is CAplus.

A detailed study of tetrathiomolybdate mediated tandem regio- and stereoselective ring opening of aziridine, disulfide formation, reduction of disulfide bond and Michael reaction in a one-pot operation is reported. This constitutes four reactions that take place in one-pot operation. In the reaction of [BnEt₃N]₄MoS₄ with an aziridine derived from cyclohexene and in the absence of Michael acceptor intermediates sulfonamidodisulfide and sulfonamidothiol were isolated and fully characterized. It has also been shown that it is possible to carry out selective opening of the aziridine ring in the presence of an epoxide. By incorporating a suitable Michael acceptor as part of the substrate, intramol. 1,4-addition could be performed, to achieve the synthesis of sulfur containing acyclic, cyclic amino acid ester derivatives and thia-bicyclo[3.3.1]nonane derivatives in good yields.

Huang, Boshi published the artcileVerifying the role of 3-hydroxy of 17-cyclopropylmethyl-4,5α-epoxy-3,14β-dihydroxy-6β-[(4′-pyridyl)carboxamido]morphinan derivatives via their binding affinity and selectivity profiles on opioid receptors, Application of 2-Chloroisonicotinic acid, the publication is Bioorganic Chemistry (2021), 104702, database is CAplus and MEDLINE.

In the present study, the role of 3-hydroxy group of a series of epoxymorphinan derivatives I (R¹ = H, OH; R² = Cl, Br, CN, Me, OMe) in their binding affinity and selectivity profiles toward the opioid receptors (ORs) has been investigated. It was found that the 3-hydroxy group was crucial for the binding affinity of these derivatives for all three ORs due to the fact that all the analogs I (R¹ = OH) exhibited significantly higher binding affinities compared to their counterpart 3-dehydroxy ones I (R¹ = H). Meanwhile most compounds carrying the 3-hydroxy group possessed similar selectivity profiles for the kappa opioid receptor over the mu opioid receptor as their corresponding 3-dehydroxy derivatives The [³⁵S]-GTPγS functional assay results indicated that the 3-hydroxy group of these epoxymorphinan derivatives I was important for maintaining their potency on the ORs with various effects. Further mol. modeling studies helped comprehend the remarkably different binding affinity and functional profiles between compound I (R¹ = H, R² = CN)(NCP) and its 3-dehydroxy analog I (R¹ = OH, R² = CN).

Xiong, Yusheng published the artcileDiscovery of a novel glucagon receptor antagonist N-[(4-{(1S)-1-[3-(3, 5-dichlorophenyl)-5-(6-methoxynaphthalen-2-yl)-1H-pyrazol-1-yl]ethyl}phenyl)carbonyl]-β-alanine (MK-0893) for the treatment of type II diabetes, COA of Formula: C9H12BClO3, the publication is Journal of Medicinal Chemistry (2012), 55(13), 6137-6148, database is CAplus and MEDLINE.

A potent, selective glucagon receptor antagonist I was discovered by optimization of a previously identified lead. Compound I is a reversible and competitive antagonist with high binding affinity (IC₅₀ of 6.6 nM) and functional cAMP activity (IC₅₀ of 15.7 nM). It is selective for glucagon receptor relative to other family B GPCRs, showing IC₅₀ values of 1020 nM for GIPR, 9200 nM for PAC1, and >10000 nM for GLP-1R, VPAC1, and VPAC2. Compound I blunted glucagon-induced glucose elevation in hGCGR mice and rhesus monkeys. It also lowered ambient glucose levels in both acute and chronic mouse models: in hGCGR ob/ob mice it reduced glucose (AUC 0-6 h) by 32% and 39% at 3 and 10 mpk single doses, resp. In hGCGR mice on a high fat diet, compound I at 3, and 10 mpk po in feed lowered blood glucose levels by 89% and 94% at day 10, resp., relative to the difference between the vehicle control and lean hGCGR mice. On the basis of its favorable biol. and DMPK properties, compound I (MK-0893) was selected for further preclin. and clin. evaluations.

Staderini, Matteo published the artcileA tripod anchor offers improved robustness of peptide-based electrochemical biosensors, Product Details of C19H14Cl2, the publication is Sensors and Actuators, B: Chemical (2018), 662-667, database is CAplus.

Peptide-based electrochem. biosensors have proven to be powerful sensing strategies for the detection of proteases and offer a highly versatile system, as simple tuning of the immobilized substrate peptide leads to a new sensing platform. The most common immobilization strategy of peptides onto an electrode surface is via a self-assembled monolayer (SAM) through a thiol group that can be readily chem. incorporated in the target peptide. However, the successful application of these platforms in complex biol. samples can be frustrated by the lack of stability of the peptide-based SAM, that can lead to false positives and limited shelf-life. Herein, we investigated the stability of a peptide-based electrochem. platform endowed with a single or a tribranched thiol group for attaching onto the electrode surface. Side-by-side comparison demonstrated that the tripod anchor generated a highly robust peptide-based electrochem. biosensor that showed improved stability when compared to the monoanchor analog, simplifying data anal. and interpretation, while showing efficient protease detection and similar sensing capabilities.
