Disclosed herein are small molecule calpain modulator compositions, pharmaceutical compositions, the use and preparation thereof. Some embodiments relate to macrocyclic α-keto amide derivatives and their use as therapeutic agents.

Chemoselective conjugation is achieved through redox reactivity by reacting an N-transfer oxidant with a thioether substrate in a redox reaction in an aqueous environment to form a conjugation product. In embodiments, Redox-Activated Chemical Tagging (ReACT) strategies for methionine-based protein functionalization. Oxaziridine (Ox) compounds serve as oxidant-mediated reagents for direct functionalization by converting methionine to the corresponding sulfimide conjugation product.

The present disclosure relates to 1,3,5-dioxazine derivatives of formula (I) capable of reducing or eliminating hydrogen sulfide and other objectionable sulfides from oil field produced hydrocarbon fluids such as petroleum, fuel oil, gasoline, diesel, liquid propane, liquid butane, an aquaculture and production/processing of syngas/natural gas. The present disclosure further provides a method for preparing 1, 3, 5-dioxazine derivatives of formula I, and a method for scavenging sulfur-based species including, but not limited to hydrogen sulfide or alkyl/aryl mercaptans from a medium.
