Leishmaniasis is a major infectious disease with hundreds of thousands of new cases and over 20,000 deaths each year. The current drugs to treat this life-threatening infection have several drawbacks such as toxicity and long treatment regimens. A library of 1.8 million compounds, from which the hits reported here are publicly available, was screened against Leishmania infantum as part of an optimization program; a compound was found with a 2-aminobenzimidazole functionality presenting moderate potency, low metabolic stability and high lipophilicity. Several rounds of synthesis were performed to incorporate chemical groups capable of reducing lipophilicity and clearance, leading to the identification of compounds that are active against different parasite strains and have improved in vitro proper-ties. As a result of this optimization program, a group of compounds was further tested in anticipation of in vivo evaluation. In vivo tests were carried out with compounds 29 (L. infantum IC50: 4.1 μM) and 39 (L. infantum IC50: 0.5 μM) in an acute L. infantum VL mouse model, which showed problems of poor exposure and lack of efficacy, despite the good in vitro potency.

A Lewis-acid promoted chemoselective condensation of 2-aminobenzimidazoles or 3-aminoindazoles with 3-ethoxycyclobutanones is presented. Diverse fused heterocycles benzo[4,5]-imidazo[1,2-a]pyrimidine and pyrimido[1,2-b]-indazole derivatives were obtained in moderate to high yields under mild conditions, the reaction mechanism of which was in sharp contrast to previous [3+3] annulation reaction of 3-ethoxycyclobutanones. (Figure presented.).

A highly efficient synthesis of 3-formyl imidazo[1,2-a]pyridine and imidazo[1,2-a]pyrimidine, under Cu-catalyzed aerobic oxidative conditions and by utilizing ethyl tertiary amines as carbon sources, is disclosed. A novel activation mode of ethyl tertiary amines in which simultaneous selective cleavage of C-C bond and C-N bond of ethyl group with molecular oxygen as terminal oxidant in this one-pot protocol is reported for the first time. This reaction features broad substrate scope, good functional group tolerance, as well as diversified and valuable products.

A series of benzothiazolyl amides and benzimidazolyl amides (6a-f) has been synthesized from the coupling reaction of substituted picolinic acid with benzothiazole and benzimidazoles, respectively. The newly synthesized compounds were evaluated for their efficacy as antimicrobial agents against various Gram-positive and Gram-negative strains of bacteria and fungal strains. Amongst these compounds 6f was found to be the most potent against Bacillus subtilis and Candida albicans. Moreover, other compounds also found to be potential antibacterial agents in comparison to the standard drugs.

Paragraph 0216; 0217; 0222; 0223, (2013/06/05)
Compounds described herein inhibit biofilm formation or disperse pre-formed biofilms of Gram-negative bacteria. Biofilm-inhibitory compounds can be encapsulated or contained in a polymer matrix for controlled release. Coatings, films, multilayer films, hydrogels, microspheres and nanospheres as well as pharmaceutical compositions and disinfecting compositions containing biofilm-inhibitory compounds are also provided. Methods for inhibiting formation of biofilms or dispersing already formed biofilms are provided. Methods for treating infections of gram-negative bacteria which form biofilms, particularly those of Pseudomonas and more particularly P. aeruginosa.

Bacterial biofilms are exceptionally difficult to clear using traditional antibiotics and constitute a significant health threat. 2-Aminobenzimidazole derivatives (see scheme) are capable of strongly inhibiting the growth of and dispersing Pseudomonas aeruginosa biofilms. These molecules were found to modulate quorum sensing in reporter strains, and represent some of strongest P. aeruginosa biofilm inhibitors known. Copyright
