COX-1
COX-1 (cyclooxygenase-1, PTGS1) is a constitutively expressed prostaglandin-endoperoxide synthase that catalyzes the conversion of arachidonic acid into prostaglandin intermediates, thereby initiating prostaglandin and thromboxane biosynthesis essential for physiological homeostasis[1][2]. Mechanistically, COX-1 participates in the cyclooxygenase and peroxidase reactions that generate prostaglandin H2, a central precursor for multiple bioactive prostanoids regulating vascular function, platelet activity, renal perfusion, and gastrointestinal integrity[1][3]. Through sustained prostanoid production, COX-1 contributes to tissue-protective and housekeeping functions across mammalian organs, including maintenance of gastric mucosal defense and thromboxane A2-dependent platelet aggregation[3][2]. In disease and pharmacological models, inhibition of COX-1 reduces prostaglandin synthesis and underlies the therapeutic actions of aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs), while also contributing to gastrointestinal adverse effects associated with nonselective COX blockade[1][2][4]. Compared with the inducible isoform COX-2, which is preferentially upregulated by inflammatory stimuli and cellular stress, COX-1 exhibits stable basal expression and is primarily associated with physiological regulation rather than acute inflammatory responses[3][2][4]. For experimental applications, selective and nonselective COX inhibitors remain important tools for dissecting prostanoid-dependent signaling pathways and distinguishing constitutive versus inducible cyclooxygenase functions in inflammation, thrombosis, and tissue homeostasis[1][3][4].

Roburic acid
0 ImagesRoburic acid acts as an anti-inflammatory, anti-tumor and osteoclastogenesis inhibitor, with a Ki of 7.066 μM against human TNF, an IC50 of 9 μM against human COX-2, and an IC50 of 5 μM against ovine COX-1. Roburic acid reduces the production of inflammatory mediators such as NO and IL-6 in macrophages by inhibiting the NF-κB and MAPK (p38/JNK) pathways. By competitively inhibiting the TNF-TNF-R1 interaction, Roburic acid blocks the downstream NF-κB signaling pathway, thereby inducing cell cycle arrest and apoptosis in cancer cells. Roburic acid specifically inhibits osteoclastogenesis and bone resorption by suppressing the RANKL/TRAF6/NF-κB/NFATc1 axis. Roburic acid can be used in research related to osteolytic diseases such as osteoporosis, colorectal cancer and inflammatory diseases.
