Irreversible inhibitors of the proline racemase unveil innovative mechanism of action as antibacterial agents against Clostridioides difficile

Proline racemases (PRAC), catalyzing the l-proline and d-proline interconversion, are essential factors in eukaryotic pathogens such as Trypanosoma cruzi, Trypanosoma vivax, and Clostridioides difficile. If the discovery of irreversible inhibitors of T.?cruzi PRAC (TcPRAC) led to innovative therapy of the Chagas disease, no inhibitors of CdPRAC have been discovered to date. However, C.?difficile, due to an increased incidence in recent years, is considered as a major cause of health threat. In this work, we have taken into account the similarity between TcPRAC and CdPRAC enzymes to design new inhibitors of CdPRAC. Starting from (E) 4-oxopent-2-enoic acid TcPRAC irreversible inhibitors, we synthesized 4-aryl substituted analogs and evaluated their CdPRAC enzymatic inhibition against eleven strains of C.?difficile. This study resulted in promising candidates and allowed for identification of (E)-4-(3-bromothiophen-2-yl)-4-oxobut-2-enoic acid 20 that was chosen for complementary in vivo studies and did not reveal in vivo toxicity.

Isocyanide-based MCRs: Diastereoselective cascade synthesis of perfluoroalkylated pyrano[3,4-c]pyrrole derivatives

The highly diastereoselective synthesis of perfluoroalkyl-containing pyrano[3,4-c]pyrroles has been accomplished via a cascade process involving Michael addition, Passerini-type reaction, Mumm rearrangement and an oxo-Diels–Alder reaction. This domino tra

Design, synthesis, and bioevaluation of a novel class of (E)-4-oxo-crotonamide derivatives as potent antituberculosis agents

A series of novel (E)-4-oxo-2-crotonamide derivatives were designed and synthesized to find potent antituberculosis agents. All the target compounds were evaluated for their in vitro activity against Mycobacterium tuberculosis H37Rv(MTB). Results reveal that 4-phenyl moiety at part A and short methyl group at part C were found to be favorable. Most of the derivatives displayed promising activity against MTB with MIC ranging from 0.125 to 4 μg/mL. Especially, compound IIIa16 was found to have the best activity with MIC of 0.125 μg/mL against MTB and with MIC in the range of 0.05–0.48 μg/mL against drug-resistant clinical MTB isolates.

Synthesis of chiral γ-lactones via a RuPHOX-Ru catalyzed asymmetric hydrogenation of aroylacrylic acids

An asymmetric hydrogenation of aroylacrylic acids catalyzed by RuPHOX-Ru catalyst has been developed, affording the corresponding chiral γ-lactones in high yields and with up to 93% ee. The methodology has the advantage of utilizing easily accessible substrates and has therefore expand the scope of the resulting chiral γ-lactones. Furthermore, high catalytic efficiency was achieved in that the reduction of both the C[dbnd]C and C[dbnd]O double bonds was achieved in one step. The current work provides an alternative and convenient pathway for the synthesis of a wide range of chiral γ-lactones.

Efficient synthesis of uracil-derived hexa- and tetrahydropyrido[2,3-d] pyrimidines

A reaction of 6-amino-1,3-dimethyluracil with 3-(hetero)aroylacrylic acids and their methyl esters leads to hexahydropyrido[2,3-d]pyrimidine-5-carboxylic acids or the corresponding methyl esters in high to excellent yields. One-pot oxidation of the acid d

2-Substituted phenyl-6-trifluoromethyl-4-pyridyl-carbinolamines

A series of 2-aryl-6-trifluoromethyl-4-pyridylcarbinolamines is herein disclosed which has value in treatment of plasmodial infections. The compounds have substituted phenyl groups at position 2- on the pyridine moiety, with the electronegative substituents present on the phenyl nuclei. The syntheses of such series is described, together with a method for separation of racemates of a representative 4-pyridylcarbinolamine type.
