Topoisomerase IV inhibitor 2 (compound 5d) is a potent inhibitor of DNA topoisomerase IV (TOPO IV), exhibiting IC50 values of 0.35 μM for TOPO IV and 0.55 μM for DNA gyrase. It also demonstrates antibacterial properties, with minimum inhibitory concentrations (MICs) of 1.985 μM against Staphylococcus aureus Newman and 0.744 μM against Escherichia coli ATCC8739 [1].

Plm IV Inhibitor-2 is a powerful inhibitor of digestive vacuole plasmepsins IV (Plm IV), displaying IC50 values of 24 nM for Plm IV, 70 nM for Plm II, and 0.3 μM for Plm I. It is used in malaria research involving Plasmodium parasites.

DPP-4-IN-2 (compound b2) is a structural analog of Alogliptin that can be used for the research of diabetes. DPP-4-IN-2 is a potent dipeptidyl peptidase 4 (DPP-4) inhibitor with an IC50 value of 79 nM [1].

SIRT1/2 Inhibitor IV (cannabinol) is a small-molecule inhibitor of SIRT1 and SIRT2 with IC50 values of 56 μM and 59 μM, respectively.

DPP IV/hCA II-IN-1 is a potent, selective inhibitor of dipeptidyl peptidase IV (DPP IV) and carbonic anhydrase (CA), exhibiting an IC50 of 0.049 μM for DPP IV and K_i values of 0.0361, 0.0428, 0.0941, 0.1328, 0.2615, and 3.034 μM for CA II, CA VB, CA VA, CA IX, CA I, and CA IV, respectively [1].

Talabostat (PT100, Val-boroPro) is a potent, nonselective and orally available dipeptidyl peptidase IV (DPP-IV) inhibitor with a Ki of 0.18 nM. Talabostat is a nonselective DPP-IV inhibitor, inhibiting DPP8/9, FAP, DPP2 and some other DASH family enzymes essentially as potently as it inhibits DPP-IV[1]. Talabostat stimulates the immune system by triggering a proinflammatory form of cell death in monocytes and macrophages known as pyroptosis. The inhibition of two serine proteases, DPP8 and DPP9, activates the proprotein form of caspase-1 independent of the inflammasome adaptor ASC[2]. Talabostat competitively inhibits the dipeptidyl peptidase (DPP) activity of FAP and CD26/DPP-IV, and there is a high-affinity interaction with the catalytic site due to the formation of a complex between Ser630/624 and the boron of talabostat[3]. Talabostat can stimulate immune responses against tumors involving both the innate and adaptive branches of the immune system. In WEHI 164 fibrosarcoma and EL4 and A20/2J lymphoma models, PT-100 causes regression and rejection of tumors. The antitumor effect appears to involve tumor-specific CTL and protective immunological memory. Talabostat treatment of WEHI 164-inoculated mice increases mRNA expression of cytokines and chemokines known to promote T-cell priming and chemoattraction of T cells and innate effector cells[3]. Talabostat treated mice show significant less fibrosis and FAP expression is reduced. Upon PT100 treatment, significant differences in the MMP-12, MIP-1α, and MCP-3 mRNA expression levels in the lungs are also observed. Treatment with PT100 in this murine model of pulmonary fibrosis has an anti-fibro-proliferative effect and increases macrophage activation[4]. [1]. Connolly BA, et al.
