In the research of covalent inhibitors targeting serine and threonine, scientists have found that the nucleophilicity of these hydroxyl groups is significantly enhanced due to the influence of their surrounding environment. This results in higher activity during catalytic reactions. Aspirin, which targets the non-catalytic domain serine (Ser529 in human COX1) of cyclooxygenase, exerts its anti-inflammatory effect through covalent binding. β-lactam antibiotics, which targets the catalytic domain serine of penicillin-binding proteins, interferes with bacterial cell wall synthesis.

Through careful selection, we constructed a structural filter containing over 110 electrophilic groups. By analyzing the electrophilic fragments selected by the structural filter, we removed any molecules with trivial or undesirable structural features. Ultimately, we obtained 3,300 fragment molecules which can target serine and threonine residues and can be used for fragment-based covalent drug discovery.

CAS No.: 1036322-26-5
Melanotan (MT)-II acetate is a melanocortin receptor agonist. Melanotan (MT)-II acetate activates melanocortin receptor 3 and melanocortin receptor 4, and stimulates the release of central endogenous oxytocin. Melanotan (MT)-II acetate reverses recognition memory impairment, increased anxiety levels and reduced exploratory tendency in zebrafish exposed to short-term high-fat diet. Melanotan (MT)-II acetate improves impaired social behavior indicators in mouse models of autism spectrum disorder. Melanotan (MT)-II acetate induces weight loss, reduces food intake and exerts anorectic effects. Melanotan (MT)-II acetate increases intracavernous pressure and erectile activity in brown rats. Melanotan (MT)-II acetate can be used in studies related to memory impairment, anxiety, reduced exploratory behavior, autism spectrum disorder, obesity and erectile dysfunction .
