Cefathiamidine is a beta-lactam antibiotic that exhibits a broad spectrum of bactericidal activity against gram-positive bacteria. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, it inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins.

Acetyl-11-keto-beta-boswellic acid (AKBA), a pentacyclic triterpene, is a component of gum resin of Boswellia serrata. It inhibits 5-lipoxygenase in a selective, enzyme directed, non-redox, and noncompetitive manner. In addition, AKBA inhibited topoisomerase I. It induces apoptosis and exerts antineoplastic properties. 5-LOXIN, a dietary supplement ingredient (Boswellia serrata extract enriched with 30% 3-O-acetyl-11-keto-beta-boswellic acid) is effective in reducing pain and improving physical functioning in osteoarthritis patients.
