El desarrollo de resistencia a los fármacos leishmanicidas representa un reto significativo en el control la leishmaniasis, debido disminución eficacia tratamientos por aparición cepas resistentes. Este estudio tuvo como objetivo analizar las tendencias investigación relacionadas con farmacorresistencia Leishmania, identificando patrones literatura producción científica, autores relevantes y actuales. Se revisaron 672 artículos indexados dos principales bases datos fuentes bibliográficas, posteriormente fueron clasificados, siguiendo metodología PRISMA. En presente trabajo se plantean dar respuestas siguientes interrogantes: 1. ¿Explorar medidas bibliométricas estudios Leishmaniasis su Fármacos? 2. ¿Cuáles son fármacos?, aplicando análisis bibliométrico. Los resultados obtenidos definen 4 áreas críticas fármacos, son: Enfermedades Tropicales Descubrimiento Fármacos, Resistencia Terapéutica Leishmaniasis, Dinámica Molecular Actividad Antileishmanial Simulación Cribado Molecular.

Perovskones, intricate triterpenoids with potent antiplasmodial activity, predominantly derive from Salvia hydrangea DC. ex Benth. In this study, ample quantities of the parent compound, perovskone (1), were isolated plant. Using (1) as a feedstock, seven semisynthetic analogues (2-8) generated via reactions like hydroxylation, elimination, and esterification. Structural characterization was performed by using 1D 2D NMR, HRMS, X-ray diffraction experiments. The compounds underwent in vitro antiparasitic testing against Leishmania donovani, Trypanosoma brucei rhodesiense, Plasmodium falciparum, cruzi. Cytotoxicity evaluation rat myoblast (L6) cells. Perovskone demonstrated excellent activity T. cruzi, showing an IC50 value 0.89 μM selectivity index (SI) 14.9. I (4) G (2) exhibited P. falciparum (IC50 values 0.03 0.08 μM, respectively), favorable SIs 843.0 80.0, comparable to those chloroquine artemisinin. M (8) displayed promising antileishmanial = 0.44 SI 22), efficacy miltefosine L. donovani 0.51 μM). We believe that current study holds immense potential for development leads drug discovery.
