Mupirocin (pseudomonic acid A, or Bactroban or Centany) is an antibiotic originally isolated from Pseudomonas fluorescens. It is used topically, and is primarily effective against Gram-positive bacteria. Mupirocin is bacteriostatic at low concentrations and bactericidal at high concentrations. Mupirocin has a unique mechanism of action, which is selective binding to bacterial isoleucyl-tRNA synthetase, which halts the incorporation of isoleucine into bacterial proteins. Because this mechanism of action is not shared with any other antibiotic, mupirocin has few problems of antibiotic cross-resistance.

Mupirocin apparently exerts its antimicrobial activity by reversibly inhibiting isoleucyl-transfer RNA, thereby inhibiting bacterial protein and RNA synthesis[1][2].

C21H40N8O6 (500.3071)

Tuftsin (L-threonyl-L-lysyl-L-prolyl-L-arginine) is a peptide related primarily to the immune system function. Tuftsin is a tetrapeptide (Thr-Lys-Pro-Arg) produced by enzymatic cleavage of the Fc-domain of the heavy chain of immunoglobulin G. It is produced primarily in the spleen. Its biological activity is related primarily to the immune system function. Tuftsin binds to specific receptors on the surface of macrophages and polymorphonuclear leukocytes, stimulating their migration, phagocytic, bactericidal, and tumoricidal activity. It also influences antibody formation. Tuftsin deficiency, either hereditary or following splenectomy, results in increased susceptibility to certain infections. Tuftsin has been chemically synthesized and it is considered for use in immunotherapy.

Medicagenate, also known as medicagenic acid, is a member of the class of compounds known as triterpenoids. Triterpenoids are terpene molecules containing six isoprene units. Medicagenate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Medicagenate can be found in a number of food items such as mountain yam, jicama, wakame, and wasabi, which makes medicagenate a potential biomarker for the consumption of these food products.
