Current medical approaches to control the Covid-19 pandemic are either to directly target the SARS-CoV-2 via innovate a defined drug and a safe vaccine or indirectly target the medical complications of the virus. One of the indirect strategies for fighting this virus has been mainly dependent on using anti‐inflammatory drugs to control cytokines storm responsible for severe health complications. We revealed the discovery of novel fused pyrrolopyrimidine derivatives as promising antioxidant and anti-inflammatory agents. The newly synthesised compounds were evaluated for their in vitro anti-inflammatory activity using RAW264.7 cells after stimulation with lipopolysaccharides (LPS). The results revealed that 3a, 4b, and 8e were the most potent analogues. Molecular docking and simulations of these compounds against COX-2, TLR-2 and TLR-4 respectively was performed. The former results were in line with the biological data and proved that 3a, 4b and 8e have potential antioxidant and anti-inflammatory effects. Graphical Abstract

Since herpes simplex virus type 1 (HSV-1) infection is so widespread, several antiviral drugs have been developed to treat it, among which are uracil nucleosides. However, there are major problems with the current medications such as severe side-effects and drug resistance. Here we present some newly synthesized cyclic and acyclic uracil nucleosides that showed very promising activity against HSV-1 compared to acyclovir.

Breast cancer is the predominant form of cancer among women and ranks as the second most prevalent cancer globally, affecting both developed and less developed countries. Presently, accessible cancer treatment methods either employ recently created, secure, and efficient chemotherapeutic medications or directly target innovative pathways that cause apoptosis. One of the indirect strategies for treating this fatal illness has mostly depended on its essential role in cell cycle arrest and apoptosis induction, as well as the antagonistic interaction between the Bcl-2 and Mcl-1 proteins, in order to avert major health repercussions. We reported that newly synthesized fused chromenopyrimidines (3a and 4a) showed potential cell cycle arrest and dual Bcl-2 and Mcl-1 inhibitory characteristics. Bcl-2 and Mcl-1 were the targets of a molecular docking procedure. The previous docking results are in line with the biological data and suggest that 3a may have promising anti-cancer activity.
