Category: naphthyridines. A couple of challenges comes to mind: improving temperature dependence of relative stabilities of polymorphs would help in identifying enantiotropic relationships. Recently I am researching about AUREUS STRESS TOLERANCE; STAPHYLOCOCCUS-AUREUS; PROTEASE; INSIGHTS; CLEAVAGE; REVEAL; ROLES, Saw an article supported by the National Mega-project for Innovative Drugs [2019ZX09721001-001-001]; National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [81973368, 81670008, 81871615]; National Key Research and Development Plan [SQ2016YFJC040104].

Through research, I have a further understanding and discovery of (R)-BoroLeu-(+)-Pinanediol trifluoroacetate

Caseinolytic protease P (ClpP) is considered as a promising target for the treatment of Staphylococcus aureus infections. In an unbiased screen of 2632 molecules, a peptidomimetic boronate, MLN9708, was found to be a potent suppressor of SaClpP function. A time-saving and cost-efficient strategy integrating in silico position scanning, multistep miniaturized synthesis, and bioactivity testing was deployed for optimization of this hit compound and led to fast exploration of structure-activity relationships. Five of 150 compounds from the miniaturized synthesis exhibited improved inhibitory activity. Compound 43Hf was the most active inhibitor and showed reversible covalent binding to SaClpP while did not destabilize the tetradecameric structure of SaClpP. The crystal structure of 43Hf-SaClpP complex provided mechanistic insight into the covalent binding mode of peptidomimetic boronate and SaClpP. Furthermore, 43Hf could bind endogenous ClpP in S. aureus cells and exhibited significant efficacy in attenuating S. aureus virulence in vitro and in vivo.

As the most studied and widely used chiral ligands, (R)-BoroLeu-(+)-Pinanediol trifluoroacetate have been rapidly developed in recent decades due to their simple synthesis to achieve excellent results in multiple reactions. Recently I am researching about BIOLOGICAL EVALUATION; 20S PROTEASOME; IN-VITRO; BORTEZOMIB; DESIGN; RESISTANCE; RISK, Saw an article supported by the National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [21877061]; Natural Science Foundation of Jiangsu ProvinceNatural Science Foundation of Jiangsu Province [BK20171448]; National and Local Joint Engineering Research Center of Biomedical Functional Materials; Priority Academic Program Development of Jiangsu Higher Education Institutions (PAPD).

Through research, I have a further understanding and discovery of (R)-BoroLeu-(+)-Pinanediol trifluoroacetate, Formula: C17H29BF3NO4

A series of novel dipeptidyl boronic acid compounds were designed, synthesized and biologically investigated for the inhibition of the 5 subunit of 20S proteasome and several compounds showed high activities with IC50 values of less than 10 nM. Some of these compounds potently inhibited the multiple myeloma (MM) cancer cell lines with IC50 values of less than 10 nM. It was reported that the inhibition of both 2 and 5 subunits strongly increased the cytotoxicity of proteasome inhibitors in solid tumor cells, so some of the compounds were evaluated for the inhibition of the 2 subunit and the solid tumor triple-negative breast cancer cell line MDA-MB-231. The results showed that three compounds were active for both the 2 subunit and the triple-negative breast cancer cell line MDA-MB-231. The in vivo pharmacokinetic results showed that compound 8t had good biological parameters for both ig and iv administrations. An in vivo pharmacodynamic experiment showed that compound 8t inhibited the 5 subunit in whole blood more greatly than the marketed MLN9708 with the same dose at different time periods. A pathological analysis indicated that the injection of compound 8t in the tumor of a triple-negative breast cancer xenograft mice model led to tumor cell necrosis, nucleus condensation, deep staining, cell fragmentation, dissolution and neutrophil infiltration compared with the control group. The data in hand showed that compound 8t might be an effective candidate for the treatment of both MM and triple-negative breast cancer.

Through research, I have a further understanding and discovery of (R)-BoroLeu-(+)-Pinanediol trifluoroacetate

Caseinolytic protease P (ClpP) is considered as a promising target for the treatment of Staphylococcus aureus infections. In an unbiased screen of 2632 molecules, a peptidomimetic boronate, MLN9708, was found to be a potent suppressor of SaClpP function. A time-saving and cost-efficient strategy integrating in silico position scanning, multistep miniaturized synthesis, and bioactivity testing was deployed for optimization of this hit compound and led to fast exploration of structure-activity relationships. Five of 150 compounds from the miniaturized synthesis exhibited improved inhibitory activity. Compound 43Hf was the most active inhibitor and showed reversible covalent binding to SaClpP while did not destabilize the tetradecameric structure of SaClpP. The crystal structure of 43Hf-SaClpP complex provided mechanistic insight into the covalent binding mode of peptidomimetic boronate and SaClpP. Furthermore, 43Hf could bind endogenous ClpP in S. aureus cells and exhibited significant efficacy in attenuating S. aureus virulence in vitro and in vivo.
