Polymyxin B Sulfate (Poly-RX) is a mixture of polymyxins B1 and B2, obtained from Bacillus polymyxa strains. They are basic polypeptides of about eight amino acids and have cationic detergent action on cell membranes. Polymyxin B Sulfate (Poly-RX) is used for infections with gram-negative organisms, but may be neurotoxic and nephrotoxic.

Lipid A-11 is a lipid component of endotoxin that is primarily responsible for the toxic properties of gram-negative bacteria. Lipid A-11 constitutes the innermost region of the lipopolysaccharide (LPS) molecule, also known as endotoxin, and its hydrophobic nature facilitates anchoring of the LPS structure into the bacterial outer membrane. Lipid A-11 plays a critical role in host-pathogen interactions, contributing to septic shock and immunological activation during bacterial infections.

Zoliprofen is 20 times more effective than ibuprofen and fenoprofen against collagen- or arachidonic acid-induced platelet aggregation in rats and rabbits. Zoliprofen was 20 times more effective than ibuprofen and fenoprofen in inhibiting endotoxin-induced diarrhoea in mice and arachidonic acid-induced acute mortality in rabbits.

Lanthanum trichloride can be used as an analytical reagent and can be used as a raw material for extracting metal lanthanum and as a petroleum cracking catalyst. Lanthanum chloride also has a certain role in the field of medicine. For example, studies have shown that the antagonistic effect of lanthanum chloride on endotoxin (LPS) in vivo effects has a certain impact on the search for new effective endotoxin antagonists, providing experimental evidence for the prevention and treatment of endotoxemia.

Betamethasone 17-Propionate is a compound used in the study of its effects on endotoxin-induced uveitis in rats, capable of inhibiting cellular infiltration into the aqueous humor when administered topically or systemically at certain doses. However, compared to some other compounds, its inhibitory effects are relatively weaker. When administered systemically, the dosage is 1mg/kg. Additionally, in in vitro interleukin-8 (IL-8) release assays, Betamethasone 17-Propionate's suppression of IL-8 release from rat peritoneal exudate cells is less effective than that of betamethasone. Moreover, the concurrent addition of betamethasone dipropionate with Betamethasone 17-Propionate reduces the suppressive effects of betamethasone on cell infiltration and IL-1β gene expression.

RGH-1875 (GYKI 39521) hydriodide is the hydriodide salt form of RGH-1875, which is an orally active antithrombotic agent. It prevents the reduction of fibrinogen levels and platelet counts induced by endotoxins, reduces levels of fibrin degradation products, and inhibits the enhancement of endotoxin-induced fibrinolytic activity in a rabbit model of endotoxin-induced disseminated intravascular coagulation. RGH-1875 is applicable for research on thrombotic disorders.

RGH-1962 is an orally active antithrombotic agent. It prevents the endotoxin-induced reduction in fibrinogen levels and platelet count, decreases fibrin degradation product levels, and inhibits the enhancement of fibrinolytic activity in an endotoxin-induced disseminated intravascular coagulation model in rabbits. RGH-1962 is applicable for research in thrombotic diseases.

HTS13286 is a novel inhibitor of AQP9. It can prevent lipopolysaccharide-induced increases in NO and reduce glucose output. HTS13286 is applicable for research in endotoxin shock.

α-Melanocyte-stimulating hormone (α-MSH) is a 13-amino acid peptide hormone produced by post-translational processing of proopiomelanocortin (POMC) in the pituitary gland, as well as in keratinocytes, astrocytes, monocytes, and gastrointestinal cells.1It is an agonist of melanocortin receptor 3 (MC3R) and MC4R that induces cAMP production in Hepa cells expressing the human receptors (EC50s = 0.16 and 56 nM, respectively).2α-MSH (100 pM) reducesS. aureuscolony formation andC. albicansgerm tube formationin vitro.3It inhibits endotoxin-, ceramide-, TNF-α-, or okadaic acid-induced activation of NF-κB in U937 cells.1α-MSH reduces IL-6- or TNF-α-induced ear edema in mice.4It also prevents the development of adjuvant-induced arthritis in rats and increases survival in a mouse model of septic shock. Increased plasma levels of α-MSH are positively correlated with delayed disease progression and reduced death in patients with HIV.1 1.Catania, A., Airaghi, L., Colombo, G., et al.α-melanocyte-stimulating hormone in normal human physiology and disease statesTrends Endocrinol.
