Serine/Threonine Focused Covalent Fragment Library

3,300 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.

HY-L081

Phosphatase Inhibitor Library

117 compounds

Protein phosphorylation is a key post-translational modification underlying the regulation of many cellular processes. Phosphatases and kinases contribute to the regulation of protein phosphorylation homeostasis in the cell. This reversible regulation of protein phosphorylation is critical for the proper control of a wide range of cellular activities, including cell cycle, proliferation and differentiation, metabolism, cell-cell interactions, etc.

Protein phosphatases have evolved in separate families that are structurally and mechanistically distinct. Based on substrate specificity and functional diversity, protein phosphatases are classified into two superfamilies: Protein serine/threonine phosphatases and Protein tyrosine phosphatases. Ser/Thr phosphatases are metalloenzymes belonging to two major gene families termed PPP (phosphoprotein phosphatase) and PPM (metal-dependent protein phosphatases), whereas protein tyrosine phosphatases (PTPs) belong to distinct classes of enzymes that utilize a phospho-cysteine enzyme intermediate as a part of their catalytic action.

MCE supplies a unique collection of 117 phosphatase inhibitors that mainly targeting protein tyrosine phosphatases (PTPs) and serine/threonine-specific protein phosphatases. MCE Phosphatase Inhibitor Library is a useful tool for phosphatase drug discovery and related research.

Aspergillomarasmine A	Human Gut Microbiota Metabolites Microorganisms Source classification Endogenous metabolite	Endogenous Metabolite
Aspergillomarasmine A is a natural aminopolycarboxylic acid with potent inhibitory activity against class B metallo-β-lactamases (MBLs). Aspergillomarasmine A inactivates MBLs by removing a catalytic Zn2+ cofactor. Aspergillomarasmine A acts as a selective Zn2+ scavenger, promoting the dissociation of the metal cofactor, thereby indirectly inactivating NDM-1. Aspergillomarasmine A causes the loss of Zn2+ ions from the low-affinity binding site of NDM-1. The action of Aspergillomarasmine A results in the rapid degradation of Zn2+-deficient NDM-1, thereby enhancing its potency as a β-lactam enhancer. The mechanism of Aspergillomarasmine A has broad applicability among different Zn2+ chelators .
