Bestatin (Ubenimex) competitively inhibits many aminopeptidases, including B, N and leucine aminopeptidases. Ubenimex is a microbial metabolite and dipeptide with potential immunomodulatory and antitumor activities. Aminopeptidases has been implicated in the process of cell adhesion and invasion of tumor cells. Therefore, inhibiting aminopeptidases may partially attribute to the antitumor effect of ubenimex. This agent also activates T lymphocyte, macrophage, and bone marrow stem cell as well as stimulates the release of interleukin-1 and -2, thus further enhances its antitumor activity.

Myoseverin B is a microtubule assembly inhibitor that impedes tubulin polymerization (IC50 = 2 μM) and generally exhibits low cytotoxicity across most cell types. It is utilized in antitumor agent research.

LC3B recruiter 2 (34R) is an LC3B recruiting agent incorporated into the autophagy-lysosome pathway degradation system (ATTEC, Autophagy-Tethering Compounds), with a direct binding affinity for LC3B. It connects via a linker to the CDK9 inhibitor SNS-032, creating an ATTEC capable of targeting and degrading the CDK9 and Cyclin T1 complex, while also inhibiting them. Consequently, LC3B recruiter 2 exerts its function through an LC3B-dependent autophagy-lysosome pathway, interfering with the cancer cell cycle progression, thereby demonstrating antitumor activity.

[Ru(phen)2(HMPIP)](PF6)2 (Compound 6A) is an antitumor agent that inhibits the proliferation and migration of liver cancer cells (HepG2), while inducing apoptosis, autophagy, cell cycle arrest, and ferroptosis. It enhances antitumor activity by stimulating immune response, leading to an increase in CD8+ T cells.

Antitumor agent-190 (Compound 26) is a hexokinase 2 (Hexokinase2) inhibitor that exhibits significant antitumor activity by targeting both microtubules and hexokinase 2 (Hexokinase2), with an IC50 value of 0.764 μM against MD-MBA-231 cells. It effectively suppresses Hexokinase2 activity, resulting in the accumulation of reactive oxygen species (Reactive Oxygen Species) and disruption of mitochondrial membrane potential (MMP), thus promoting apoptosis and causing cell cycle arrest.

Antitumor agent-165 (Compound 10l) is an effective inhibitor of focal adhesion kinase (FAK). It exhibits significant antiproliferative effects against CAPAN-1, PANC-1, PATU-T, SUIT-2, BxPC-3, PDAC-3, and PANC-1 GR cell lines, with IC50 values ranging from 1.04 to 3.44 μM.
