Graphitic carbon nitride (g-C3N4) is a metal-free heterogeneous catalyst that has attracted attention because of its good chemical stability, cost-effectiveness, and environmental friendliness. In the work presented herein, F,O,S-codoped was synthesized by heating mixture melamine cyanurate trifluoromethanesulfonic acid at 550 °C for 50 min. The obtained product characterized transmission elect...

Introduction: This work aims to develop an efficient green synthetic procedure and cytotoxicity evaluation of benzoxazole derivatives, essential building block in medicinal chemistry research owing its broad range pharmacological properties, especially anticancer activity. Methods: The microwave-assisted condensation reaction between 2-amino-4-methylphenol aromatic aldehydes using iodine as the...

Damage resulting from the incidence of ultraviolet (UV) radiation on skin is common nowadays, with UVB (290-320 nm) and UVA (320-400 responsible for photoaging, sunburn carcinogenesis. For this reason, sunscreens represent products growing interest to prevent such damage. However, there are few organic filters marketed worldwide photostability effectiveness at wavelengths greater than 340 nm (l...
