This product is metabolized to (betaR,deltaR)-2,3-bis(4-fluorophenyl)-beta,delta-dihydroxy-5-(1-methylethyl)-4-[(phenylamino)carbonyl]-1H-pyrrole 1 heptanoic acid which is used as an analytical standard for HPLC.

Surfactin is a cyclic lipopeptide that has been found in urine and has shown potential as an anticancer agent. It has been shown to inhibit kinases, including indirubin and Chinese hamster ovary cell tumor kinase, which are involved in cancer cell proliferation. Surfactin analogs have also been developed as inhibitors of cancer cell growth and inducers of apoptosis. In addition to its anticancer properties, surfactin has been found to have antimicrobial activity against a variety of bacteria, including Clostridium perfringens. Overall, surfactin shows promise as a multifunctional therapeutic agent with potential applications in both cancer treatment and microbial control.

Trifenofos is a potent protein kinase inhibitor that has shown promising anticancer activity in preclinical studies. It targets specific kinases involved in tumor growth and survival, leading to apoptosis or programmed cell death of cancer cells. Trifenofos is an analog of a natural toxin found in Chinese urine, which has been used for centuries in traditional medicine to treat various ailments. In addition to its anticancer properties, trifenofos also shows potential as an inhibitor of other diseases involving abnormal protein kinase activity. Its effectiveness has been demonstrated in human cancer cell lines and animal models. With its ability to selectively target cancer cells, trifenofos holds great promise as a potential therapeutic agent for the treatment of various cancers.

L-693,403 Maleate is an analytical and research chemical with a purity of > 99%. L-693,403 Maleate is used as an impurity standard for HPLC analysis and drug development. It can also be used as a reference standard in the production of APIs. L-693,403 Maleate is an impurity in the synthesis of several drugs, including clozapine, fluoxetine, and loratadine. The natural form of L-693,403 Maleate can be found in the leaves of the plant Acacia holosericea. Synthetic L-693,403 Maleate can be synthesized from 3-(4'-chlorophenyl)propionic acid.

1-(3'-Pyridylmethyl)-3-(4'-nitrophenyl)urea is a medicinal compound that has been used in Chinese traditional medicine for its tumor-fighting properties. It acts as a potent inhibitor of protein kinases, which are enzymes involved in cell signaling and proliferation. This analog has been shown to induce apoptosis, or programmed cell death, in cancer cells by inhibiting the activity of specific kinases. The compound has also demonstrated anticancer activity in human cancer cell lines and may have potential as a therapeutic agent for the treatment of various types of cancer.
