NNK is a nicotinic nitrosylated derivative. It activates ERK1 2 and PKCα, and activates Bcl2 phosphorylation at Ser70, as well as c-Myc at Thr58 and Ser62.It can be used to construct mouse models of lung cancer, as well as to induce proliferation and survival of human lung cancer cells.

Lipopolysaccharides (LPS) derived from Escherichia coli 055:B5, are a unique component of the cell wall of Gram-negative bacteria. They are composed of three regions: lipid A, oligosaccharide core, and O-specific polysaccharide (O-antigen). Lipopolysaccharides help maintain the integrity of the cell outer membrane and protect bacteria from damage by bile salts and lipid antibiotics. Lipopolysaccharides are highly immunogenic antigens that can enhance immune responses and can be used to construct inflammatory models.

Semaxinib (SU5416) is a potent and selective VEGFR2 inhibitor (IC50: 1.23 μM), exhibiting a 20-fold greater selectivity for VEGFR2 over PDGFRβ, with no activity against InsR, EGFR, and FGFR. Semaxinib reversibly inhibits ATP binding to the tyrosine kinase domain of VEGFR2, potentially inhibiting VEGF-stimulated endothelial cell migration and proliferation, thereby reducing tumor microvasculature.

Doxycycline calcium, a broad-spectrum antibiotic and metalloproteinase (MMP) inhibitor, demonstrates efficacy in inhibiting bacterial growth and cancer cell proliferation, as evidenced by multiple studies [1] [2] [3] [4] [5]. This compound is active when administered orally.

Lactacystin is a natural non-peptide proteasome inhibitor and highly specific anticancer drug that controls the UPS of cellular protein turnover and inhibits alkaline cell proliferation, and is able to be used as a model for studying dementia, induces neurite outgrowth and transiently elevated levels of cAMP, inhibits angiogenesis, triggers apoptosis in glioma cells, and can penetrate the blood-brain barrier (BBB).
