PC 190723 is a synthetic chemical compound, which is derived through targeted chemical synthesis processes involving precise organic reactions. Its mode of action involves disrupting cellular division by inhibiting specific protein functions essential for the mitotic process. This molecular interaction results in potent effects on cell division, making it a valuable tool for studying cellular mechanics and developing therapeutic strategies.

Oxacillin sodium is a beta-lactam antibiotic with action on bacterial cell wall synthesis and is used for treating infections caused by penicillin-resistant Staphylococcus aureus.

An aminoglycoside antibiotic.  Found applications in treatment of UTi's as it decreases the ability of bacteria to make protein.

10, 11-Dehydrocurvularin is a fungal phytotoxin with heat shock response and immune-modulatory activitie. Curvularins inhibit the expression of the inducible nitric oxide synthase (iNOS), thereby acting as anti-inflammatory agents and immune system modulators

6'-N-Cbz-kanamycin A is a semi-synthetic aminoglycoside antibiotic derivative, specifically a Cbz (carbobenzyloxy) protected form of kanamycin A. It is derived from the natural product kanamycin, which is an antibiotic obtained from the bacterium *Streptomyces kanamyceticus*. The modification involves the introduction of a protective Cbz group at the 6' position, which can improve solubility, stability, or enable further chemical modifications.

Hypothemycin is a natural product that serves as a potent inhibitor of protein kinases. It is derived from the fungus Hypomyces subiculosus and belongs to the class of resorcylic acid lactones. Its mode of action involves binding covalently to the ATP-binding site of kinases, leading to the inhibition of their activity. This covalent modification is achieved through the formation of a Michael-type addition with a reactive ene-diene functionality within its structure. By targeting these critical enzymes, hypothemycin disrupts key signaling pathways that are essential for cell growth and proliferation.

Aclacinomycin HCl is a cytotoxic antibiotic that inhibits the growth of tumor cells. It has been shown to induce apoptosis in human leukemia cells by altering the transmembrane potential and inhibiting cell proliferation. Aclacinomycin HCl also induces DNA damage response, which leads to caspase activities and cell death. This drug is highly selective for tumor cells, with no effect on normal cells. It has been shown to be effective against primary liver cancer in animal models, as well as developmental disorders such as autism spectrum disorder (ASD).

Biotinyl tobramycin amide is a biotinylated form of the antibiotic tobramycin, which is derived from the actinobacterium Streptomyces tenebrarius. It features a tobramycin core, a potent aminoglycoside antibiotic, chemically linked to biotin. This modification allows for the specific attachment to avidin or streptavidin-labeled probes due to the strong biotin-streptavidin interaction, facilitating various labeling and detection techniques in research.

Desmethyl doxorubicin oxalate is an anthracycline-type chemotherapeutic agent, which is derived from the naturally occurring antibiotic doxorubicin. This compound comprises a desmethylated form of doxorubicin combined with oxalate. Its mode of action involves intercalating DNA strands and inhibiting topoisomerase II, thereby disrupting DNA replication and transcription. This interference leads to the inhibition of cancer cell proliferation and induces apoptosis.

2'-Deoxycoformycin is a potent adenosine deaminase inhibitor, which is derived from the fermentation of Streptomyces antibioticus, a species of actinomycete bacteria. This compound acts by specifically inhibiting the enzyme adenosine deaminase, leading to an accumulation of toxic deoxyadenosine triphosphate in lymphocytes. This buildup hinders DNA synthesis, effectively suppressing the proliferation of lymphoid cells.
