Eighteen novel benzamidine derivatives containing 1,2,3-triazole moieties were synthesized. The in vitro and in vivo fungicidal acitivities of the title compounds and the arylamidine intermediates against Colletotrichum lagenarium and Botrytis cinerea were tested. The synthesized benzamidines exhibited weak antifungal activities in vitro against the tested fungi, but some of the compounds showed excellent activities in vivo to the same strains. Among the compounds tested, 9b showed 79% efficacy in vivo against C. lagenarium at a concentration of 200 μg/mL, and the efficacy of compound 16d (90%) toward the same strain was even superior than that of the commercial fungicide carbendazim (85%).

Leishmaniasis, a neglected tropical disease caused by Leishmania parasites, continues to pose global health challenges. Current treatments face issues like resistance, safety, efficacy, and cost. This review covers the discovery, mechanisms of action, clinical applications, and limitations of key antileishmanial agents: pentavalent antimonials, amphotericin B, miltefosine, paromomycin, and pentamidine.

A facile, cost-effective, and sustainable synthesis of substituted triazines from primary alcohols by newly synthesized nickel pincer-type complexes (-) has been described. Herein, we report the synthesis of a set of three well-defined Ni(II) O^N^O pincer-type complexes, structurally characterized by analytical, spectral, and X-ray diffraction techniques. Further, the nickel complexes are explored as efficient catalysts (4 mol %) for the construction of 2,4,6-substituted 1,3,5-triazines from readily available alcohols via an acceptorless dehydrogenative coupling (ADC) strategy.

The significant synthetic potential and reactivity of tetracyanoethylene (TCNE) have captured the interest of numerous chemical communities. One of the most promising, readily achievable, yet least explored pathways for the reactivity of TCNE involves its interaction with arylamines. Typically, the reaction proceeds via tricyanovinylation (TCV); however, deviations from the standard chemical process have been observed in some instances.

A constant current electrochemical approach for the synthesis of 1-aminoisoquinoline derivatives through the Ru(II)-catalyzed annulation of benzamidine hydrochlorides with alkynes is reported herein. This method produces good yields of naphthyridine-based compounds Ru(II)-catalyzed C-H bond cleavage, leading to the formation of new C-C and C-N bonds in a one-pot manner. Notably, the synergy of electricity and Ru catalysis offers broad reaction compatibility, accommodating a wide range of substrates with diverse steric and electronic properties.

Article Synopsis
- - This study evaluated the effectiveness of standard treatments for cutaneous leishmaniasis in rural Colombia, using a community-based approach and the Guaral+ST mobile health app to assist in patient care and data collection from January 2018 to September 2021.
- - A total of 231 participants received varous antileishmanial treatments, with cure rates at 90 to 180 days being: 86.3% for miltefosine, 77.6% for meglumine antimoniate, and 73.1% for pentamidine; adverse drug reactions were noted in 32% of patients.
- - Findings indicate that standard treatments are effective in rural endemic areas, and that mobile health
