A series of eight substituted bis-2-hydroxy-1,4-naphthoquinone derivatives was synthesized through lawsone condensation with various aromatic and aliphatic aldehydes under mild acidic conditions. The title compounds were evaluated for antileishmanial activity in vitro against Leishmania amazonensis and Leishmania braziliensis promastigotes; six compounds showed good activity without significant toxic effects. The compound with the highest activity was used for an in vivo assay with Leishmania amazonensis.

This report explores the potential of novel 6-aryloxy-2-aminopyrimidine-benzonitrile scaffolds as promising anti-infective agents in the face of the increasing threat of infectious diseases. Starting from 2-amino-4,6-dichloropyrimidine, a series of 24 compounds inspired from the antiviral drugs dapivirine, etravirine, and rilpivirine were designed and synthesized via a two-step reaction sequence in good yields. Biological testing of synthetic analogs revealed potent inhibition against both viral and tuberculosis targets.

The functional units of natural photosynthetic systems control the process of converting sunlight into chemical energy. In this article, we explore a series of chemically and structurally modified bacteriochlorophyll and chlorophyll pigments through computational chemistry to evaluate their electronic spectroscopy properties. More specifically, we use multiconfigurational and time-dependent density functional theory methods, along with molecular dynamics simulations, to compute the models' energetics both in an implicit and explicit solvent environment.

An efficient synthesis of a series of uracil analogous was performed to obtain new potential anticancer agents. The cytotoxic effect of the synthesized derivatives was assessed in vitro against three cancer cell lines, namely hepatic cancer (HepG-2), colon cancer (HCT-116), and breast cancer (MCF-7). Among the tested compounds, 5, 11 and 15 stood as potent uracil derivatives with pan cytotoxicity against the 3 cell lines out-performing the reference compound 5-FU.

A series of 2,4-disubstituted pyrimidine derivatives bearing 5-substituted-1,3,4 thidiazole were devised and synthesized based on the binding mode of the approved drug Osimertinib with the ATP competitive site of EGFR-L858R/T790M in order to increase selectivity towards double mutant EGFR and potent antitumor activity. Their cellular bioactivity and corresponding enzyme inhibition were studied, and it was revealed that several compounds had significant biological activity and selectivity when compared to the control compounds. One of the most promising compound 8, substantially suppressed the proliferation of H1975 cells and showed significant inhibition of double mutant EGFR-L858R/T790M TK with IC values of 0.
