Newer Pyrrole-Chromones Chalcones (I–VII) were prepared by a simple method. among the series of compounds, compound −1 which was synthesized with 30 % of NaOH solution, at temperature of 60–65 °C with twelve hours of reaction time resulted in good yield. While, the other compounds under same and varying conditions resulted in less yield. Existing reports showed that this group of compounds showed insulysin inhibition, interleukin antagonist, and membrane integrity agonist activities. The proteins EGFR and HER-2 which are over expressed in breast cancer, in In silico studies with the titled compounds showed strong binding affinity when compared to the standard drug tamoxifen, which clearly indicate that these compounds possess anti-breast cancer activity. Hence, it can be concluded that these compounds has the potential to develop as anti-breast cancer drugs.

Existing of a cell depends on the pyrimidine moiety; it controls many functions which lead to alter the action of organs. Herein, we demonstrate the synthesis, biological evolution of newer pyrimidins. Titled compounds are formed with good yields, there In-silico studies indicating good drug likeness, drug score. The In- vitro cell viability studies using lipofectamine 2000 as reference, reveals that IC50 values for pyrimidine-II, III against GL261, pyrimidine- VIII,IX against 4 T1 Celline shows prominent results.

An efficient eco-friendly method, with less hazardous chemicals, developed for the deformylation and followed by halogenation of 3-formylchromones by applying easily available Oxone as oxidising agent and NaX as a halogenating source. Many of 3- halochromone derivatives (20 compounds) were obtained with good yields, applicable in halogenations at different levels micro to macro levels.
