HY-136720

ZXX2-77	COX	Others
ZXX2-77 is a cyclooxygenase-1 (COX-1) selective inhibitor belonging to the benzenesulfonylanilide class of compounds. It is reported as a novel analgesic that does not cause gastric damage. ZXX2-77 has a weak analgesic effect but exhibits potent COX-1 inhibitory activity in vitro. The low oral absorption rate of ZXX2-77 leads to its weak analgesic effect in vivo. At a dose of 30 mg/kg, the maximum plasma concentration of ZXX2-77 (1.2 mM) did not reach its COX-1 IC50 value (3.2 mM). In contrast, its derivative ZXX2-79, although weaker in vitro COX inhibitory activity, is better absorbed, exhibits stronger analgesic effect and hardly causes gastric damage. These findings suggest that ZXX2-77 and its derivatives as COX-1 selective inhibitors may become effective analgesics that do not cause gastric damage.

Non-steroidal Anti-Inflammatory Compound Library

627 compounds

Non-steroidal anti-inflammatory drugs (NSAIDs) are members of a therapeutic drug class with potent anti-inflammatory, analgesic and antipyretic activity, and are among the most widely used drugs worldwide. The most prominent NSAIDs are aspirin, ibuprofen, and naproxen.

The main mechanism of action of NSAIDs is the inhibition of the enzyme cyclooxygenase (COX), based on which NSAIDs can be classified into two types: non-selective and COX-2 selective. Most NSAIDs are non-selective and inhibit both COX-1 and COX-2 activity.

MCE offers a unique collection of 627 non-steroidal compounds with identified anti-inflammatory activity. MCE non-steroidal anti-inflammatory library is a useful tool for the study of anti-inflammatory drugs and pharmacology.

Serine/Threonine Focused Covalent Fragment Library

3,208 compounds

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.
