Cholesteryl ester transfer protein (CETP) represents one of the key regulators of the homeostasis of lipid particles, including high-density lipoprotein (HDL) and low-density lipoprotein (LDL) particles. Epidemiological evidence correlates increased HDL and decreased LDL to coronary heart disease (CHD) risk reduction. This relationship is consistent with a clinical outcomes trial of a CETP inhibitor (anacetrapib) combined with standard of care (statin), which led to a 9% additional risk reduction compared to standard of care alone. We discuss here the discovery of MK-8262, a CETP inhibitor with the potential for being the best-in-class molecule. Novel in vitro and in vivo paradigms were integrated to drug discovery to guide optimization informed by a critical understanding of key clinical adverse effect profiles. We present preclinical and clinical evidence of MK-8262 safety and efficacy by means of HDL increase and LDL reduction as biomarkers for reduced CHD risk.
Intermediate for preparing halichondrin compound and preparation method thereof
-
Paragraph 0132-0135, (2020/07/07)
The invention relates to an intermediate for preparing a halichondrin compound and a preparation method thereof. The invention particularly relates to an intermediate for preparing halichondrin, eribulin or analogues thereof, and a preparation method and application of the intermediate. The intermediate as well as the preparation method and application thereof are used for constructing C20-C26 structural fragments of the halichondrin compound. The initial raw materials of the synthesis route are cheap, easy to obtain, stable in source and reliable in quality; the structural characteristics ofreactants are fully utilized in the selection of a chiral center construction method, so that the synthesis efficiency is practically improved, and the difficulty and risk of product quality control are reduced; and the use of a high-toxicity and expensive organic tin catalyst is avoided, so that the cost and the environmental friendliness are remarkably improved.

Nucleophilic halo-michael addition under lewis-base activation
Laina-Martín, Víctor,Pérez, Ignacio,Fernández-Salas, Jose A.,Alemán, José
supporting information, p. 12936 - 12939 (2019/11/05)
A simple and general conjugate nucleophilic halogenation is presented. The THTO/halosilane combination has shown the ability to act as a nucleophilic halide source in the conjugate addition to a variety of Michael acceptors. In addition, a straightforward diastereoselective halogen installation using α,β-unsaturated acyloxazolidinones as platforms has been developed.
Visible light photocatalytic asymmetric synthesis of pyrrolo[1,2-: A] indoles via intermolecular [3+2] cycloaddition
Casado-Sánchez, Antonio,Domingo-Legarda, Pablo,Cabrera, Silvia,Alemán, José

G protein-coupled receptor 40 (GPR40) has become an attractive target for the treatment of diabetes since it was shown clinically to promote glucose-stimulated insulin secretion. Herein, we report our efforts to develop highly selective and potent GPR40 agonists with a dual mechanism of action, promoting both glucose-dependent insulin and incretin secretion. Employing strategies to increase polarity and the ratio of sp3/sp2 character of the chemotype, we identified BMS-986118 (compound 4), which showed potent and selective GPR40 agonist activity in vitro. In vivo, compound 4 demonstrated insulinotropic efficacy and GLP-1 secretory effects resulting in improved glucose control in acute animal models.

The first palladium-catalyzed diastereoselective conjugate addition of arylboronic acids to chiral imides is reported. The catalytic system employing 4-tert-butyloxazolidin-2-one as the chiral auxiliary in a mixed solvent system of MeOH/H2O (1:3) under an air atmosphere provides the optically active 3-arylbutanoic acid derivatives in excellent yields with high diastereoselectivity.
