Piritrexim (BW 301U) is an orally available fat-soluble dihydrofolate reductase inhibitor with pulmonary toxicity used in the study of uroepithelial carcinoma and metastatic breast cancer.

Phosphoramide mustard cyclohexanamine is the active metabolite of cyclophosphamide, an alkylating agent that cross-links DNA strands, organizes cell division and causes cell death, and has antitumor activity.

1. 7-Ethylcamptothecin has the superior antitumor activity than CPT. (a). 7-Ethylcamptothecin has a stronger growth-inhibiting activity against tumor cells. (b). 7-Ethylcamptothecin remains in the intestinal tract for a longer time and in higher amounts when administered in vivo.

CB1954(Tretazicar (NSC-115829)), an anticancer prodrug, is activated by NAD(P)H quinone oxidoreductase 2. It is converted in the presence of the enzyme NQO2 and co-substrate caricotamide ( EP-0152R) (EP) into a potent cytotoxic bifunctional alkylating agent.

(E)-5-Octadecene ((E)-Octadec-5-ene) functions as a sex pheromone or a related chemical compound, interfering with the sexual attraction of female Chilo suppressalis Walker, known as the rice borer moth [1].

1-Hydroxyguanidine sulfate is an antitumor agent that inhibits the growth of mastocytoma P815 cells, leukemia P388 cells, leukemia L1210 cells, and Walker 256 carcinosarcoma cells. Additionally, this compound exhibits antiviral (antiviral) activity.

Lipopolysaccharides, fromProteus mirabilis, are endotoxins derived from the bacterium Proteus mirabilis, functioning as TLR-4 activators and featuring an S-type LPS structure. They play a role in activating pathogen-associated molecular patterns (PAMP) and inducing cell-extracellular vesicle release. These lipopolysaccharides have a classic tripartite structure: O antigen, core oligosaccharide, and lipid A. Proteus mirabilis is a primary pathogen responsible for urinary tract infections and has potential links to rheumatoid arthritis. Additionally, Lipopolysaccharides, fromProteus mirabilis, exhibit promising antitumor effects, showing in vivo inhibitory activity against solid tumors such as meningeal sarcoma and Walker carcinoma.
