The expansion of chemical space associated with ubiquitous motifs is key to unleash new properties and functions. In this context, alkynamides, prevalent in numerous drugs and materials, represent an untapped resource. We herein report the first synthetic access to N-trifluoromethyl alkynamides. Our strategy relies on a mild and operationally simple Ni-catalyzed coupling of N-CF3 carbamoyl fluorides with alkynyl silanes. The synthesized N-CF3 alkynamides proved to be highly robust and readily functioned as a platform to unlock access to valuable derivatives, such as N-CF3 decorated alkenyl amides, oxindoles, or quinolones, all of which were inaccessible to date.

Reported herein is the first efficient strategy to synthesize a broad range of unsymmetrical N-CF3 hydrazines, which served as platform to unlock numerous currently inaccessible derivatives, such as tri- and tetra-substituted N-CF3 hydrazines, hydrazones, sulfonyl hydrazines, and valuable N-CF3 indoles. These compounds proved to be remarkably robust, being compatible with acids, bases, and a wide range of synthetic manipulations. The feasibility of RN(CF3)-NH2 to function as a directing group in C?H functionalization is also showcased.

There are currently no drugs available for the treatment of enterovirus (EV)-induced acute and chronic diseases such as the common cold, meningitis, encephalitis, pneumonia, and myocarditis with or without consecutive dilated cardiomyopathy. Here, we report the discovery and characterization of pyrazolopyrimidines, a well-tolerated and potent class of novel EV inhibitors. The compounds inhibit the replication of a broad spectrum of EV in vitro with IC50 values between 0.04 and 0.64 μM for viruses resistant to pleconaril, a known capsid-binding inhibitor, without affecting cytochrome P450 enzyme activity. Using virological and genetics methods, the viral capsid was identified as the target of the most promising, orally bioavailable compound 3-(4-trifluoromethylphenyl)amino-6-phenylpyrazolo[3,4-d]pyrimidine-4-amine (OBR-5-340). Its prophylactic as well as therapeutic application was proved for coxsackievirus B3-induced chronic myocarditis in mice. The favorable pharmacokinetic, toxicological, and pharmacodynamics profile in mice renders OBR-5-340 a highly promising drug candidate, and the regulatory nonclinical program is ongoing. Curing the common cold! A cluster of pyrazolopyrimidines with potent broad-spectrum activity against enteroviruses was discovered. Extensive structure-property relationship analyses led to the identification of 3-(4-trifluoromethyl-phenyl)amino-6-phenylpyrazolo[3,4-d]pyrimidine-4-amine, shown to be a blocker of the viral capsid protein, as a lead compound for drug development with favorable physicochemical, pharmacokinetic, and toxicological properties.

A series of thiourea and nicotinamide-containing sorafenib analogs (7a-n) were designed and synthesized and their antiproliferative activities were tested against HCT116, MDA-MB-231, PC-3 and HepG2 cell lines. Most of the compounds showed potent activities against the four cell lines, compound 7h showed better activities than sorafenib against all four cell lines, and compounds 7a and 7e showed better activities against HCT116 and MDA-MB-231 cell lines. The anti-angiogenic activities of 7e and 7h were also better than that of sorafenib in both in vitro HUVEC tube formation assay and ex vivo rat thoracic aorta ring assay.

A series of novel sorafenib derivatives containing diaryl thiourea and thioether, 9a-u, was designed and synthesized, and their antiproliferative activities against HCT116 and MDA-MB-231 cell lines were also evaluated and described. Most compounds exhibited potent antiproliferative activity against HCT116 cells with IC50 = 1.8-80.4 μM. Compounds 9p, 9r, and 9s demonstrated competitive antiproliferative activities to sorafenib, against all two cancer cell lines. The structures of all the newly synthesized compounds were determined by 1H NMR, 13C NMR, and HRMS, and compound 9n was characterized by single-crystal X-ray diffraction. Primary structure-activity relationships (SAR) have also been established.

A series of novel sorafenib derivatives, 9a-w, was designed and synthesized in high yields using various substituted anilines, and their antiproliferative activities against HCT116, PC-3 and MDA-MB-231 cell lines were also evaluated and described. All compounds exhibited potent antiproliferative activity against HCT116 and PC-3 cells with IC50 = 2.8-52.0 and 2.2-45.6 μM; compounds 9p and 9q demonstrated competitive antiproliferative activities to sorafenib against all three cancer cell lines, the cytotoxicity of compound 9r is more potent than that of sorafenib. Compounds (9g, 9p, 9q and 9r) were chosen for further evaluation of the anti-angiogenesis activity, and showed the inhibition of sprout formation from aortic ring ex vivo. The structures of all the newly synthesized compounds were determined by 1H NMR, 13C NMR and HRMS.
