Leishmaniasis is one of the most important neglected tropical diseases according to the World Health Organization. The available drugs are expensive, not sufficiently effective, have serious cytotoxic effects and parasitic resistance has increased in the last years. In the present work, a virtual screening protocol was used to identify new natural compounds potentially active against Leishmania spp. using machine learning-based models. Three vegetable origin compounds were selected by using a multiclassifier composed by models developed with k-nearest neighbor, classification tree, Multilayer perceptron and Support Vector Machine; all these models for Leishmania amazonensis promastigote form were developed with WEKA software. The selected compounds showed in vitro activity against L. amazonensis (MHOM/BR/77/LTB0016) promastigotes with CI50 lower than 1 µg/mL using 96-well plates and resazurine fluorescence method.
Now we closed the publication phase and launched the post-publication phase of the conference.
REVIEWWWERS'08 Brainstorming Workshop is Now Open from 2023-Jan-01 to 2023-Jan-31.
MOL2NET Committee, Authors, and Validated Social Media Followers Worldwide ... are invited to Post Moderated Questions/Answers, Comments, about papers.
These are my Questions (Q) to you, please kindly post your public Answers (A) below to promote scientific discussion and training of conference readers :
Q1. How does the in vitro evaluation of the compounds compare to their predicted activity based on the QSAR models?
Q2. What are the potential side effects or toxicity of the three active compounds in humans or other organisms?
Thank you for your kind support. Please make questions to other papers in different Mol2Net congresses
