Tuberculosis (TB) remains a significant global health problem for which new therapeutic options are sorely needed. The ability of the causative agent, Mycobacterium tuberculosis, to reside within host macrophages and form biofilm-like communities contributes to the persistent and drug-tolerant nature of the disease. Compounds that can prevent or reverse the biofilm-like phenotype have the potential to serve alongside TB antibiotics to overcome this tolerance, and decrease treatment duration. Using Mycobacterium smegmatis as a surrogate organism, we report the identification of two new 2-aminoimidazole compounds that inhibit and disperse mycobacterial biofilms, work synergistically with isoniazid and rifampicin to eradicate preformed M. smegmatis biofilms in vitro, are nontoxic toward Galleria mellonella, and exhibit stability in mouse plasma.

A number of novel 2-(2-arylmorpholino-4-yl)ethyl 1-(4-chlorobenzoyl)-5- methoxy-2-methyl-1H-indol-3-acetate hydrochlorides were synthesized and tested for their cyclooxygenase (COX-1 and COX-2) inhibition properties in vitro. Many of these compounds exhibited moderate to good selective COX-2 inhibition, and subtle structural changes in the substituents on the side chain of the ester moiety altered the inhibitory properties significantly. 2-[2-(4-Butoxyphenyl) morpholino-4-yl]ethyl 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-acetate hydrochloride (1f), showed good selective COX-2 inhibitory activity (Selective index (SI) 182), which is comparative with celecoxib (SI 214), a COX-2 inhibitor of diarylpyrazoles. While 2-[2-(2,4-dichloro-5-fluorophenyl)morpholino-4-yl] ethyl 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-acetate hydrochloride (1g), showed greater selective COX-2 inhibitory activity (SI 358) than celecoxib. Both compounds were identified as compromising derivatives in this class to reduce the side effects generated by nonsteroidal anti-inflammatory drugs (NSAIDs) indomethacin.

In a previous paper, we reported the N-hydroxyformamidine derivative HET0016 as a potent and selective 20-HETE synthase inhibitor. Despite its attraction as a potential therapeutic agent for cerebral diseases, the preparation of an injectable formulation
Process for producing optically active carbinols
-
, (2008/06/13)
The present invention relates to a process for producing optically active halomethyl phenyl carbinols of the formula (1), comprising reducing halomethyl phenyl ketones of the formula (2) using an asymmetric reducing agent obtained from boranes and optically active α-phenyl-substituted-β-amino alcohols of the formula (3) or optically active α-non-substituted-β-amino alcohols of the formula (4). The present invention further relates to a process for producing optically active carbinols, comprising reacting a prochiral keytone with an asymmetric reducing agent obtained from optically active β-amino alcohols of the formula (5), a metal boron hydride and Lewis acid or lower dialkyl sulfuric acid. All of the formulas (1) to (5) are the same as shown in the specification.
