DPP-9 Inhibitor

Anagliptin (SK-0403) is a highly selective, potent, orally active inhibitor of dipeptidyl peptidase 4 (DPP-4), with an IC₅₀ of 3.8 nM, and less selective at DPP-8 and DDP-9 with IC₅₀s of 68 nM and 60 nM, respectively.

NZ-97 is a locally deliverable, lung-retaining dipeptidyl peptidase 4 (DPP4) inhibitor with an IC₅₀ of 18 nM. It exhibits selectivity for DPP8 and DPP9 (with IC₅₀ values of 1.3 μM and 0.6 μM, respectively). NZ-97 inhibits the DPP4 pool in lung-resident cells and epithelial lining fluid, elevates IL-6 and IGF-1 levels, and induces the expansion of type 2 alveolar epithelial cells (AEC2). NZ-97 reduces protein content in bronchoalveolar lavage fluid (BALF), ameliorates lung injury and alleviates pulmonary fibrosis. NZ-97 shows tolerability in untreated Mus musculus mice after intratracheal administration, and does not alter the proliferation or differentiation of lung fibroblasts. NZ-97 can be used in studies related to idiopathic pulmonary fibrosis, acute lung injury and emphysema.

Anagliptin (SK-0403) hydrochloride is a highly selective, potent, orally active inhibitor of dipeptidyl peptidase 4 (DPP-4), with an IC₅₀ of 3.8 nM, and less selective at DPP-8 and DDP-9 with IC₅₀s of 68 nM and 60 nM, respectively.

DPP9-IN-2 is a selective, potent and orally active inhibitor of Dipeptidyl Peptidase 9 (DPP9 ) with an IC₅₀ of 12.9 nM. DPP9-IN-2 shows a SI of 59 over DPP8, and shows no significant inhibitory activity against related peptidases including DPP2, DPP4, FAP, and PREP. DPP9-IN-2 can induce cancer cells pyroptosis and has weak synergistic anti-HIV-1 activity when combined with non-nucleoside reverse transcriptase inhibitor. DPP9-IN-2 can be used for the researches of cance rand infection.

DPP-8/9 probe-1 (compound 20) is a fluorescent probe targeting Dipeptidyl Peptidase DPP8/9, which can be selectively labeled and visualized in vitro by fluorescence microscopy Active DPP8/9. DPP-8/9 probe-1 contains a nitrobenzoxadiazole (NBD) tag and has high affinity and selectivity for DPP8/9 over related S9 family members (IC₅₀ of 210 nM and 15 nM, respectively).

5-Hydroxy saxagliptin hydrochloride is an active metabolite of Saxagliptin (HY-10285) and a potent and selective DPP-4 inhibitor. 5-Hydroxy saxagliptin hydrochloride has K_i values of 2.6 nM and 2.9 nM for humans and cynomolgus monkeys, respectively. 5-Hydroxy saxagliptin hydrochloride can be used in the research of type 2 diabetes mellitus.

BMS-767778 is an orally active and selective DPP4 inhibitor with K_i values of 0.94 nM, 4.9, 3.2 nM for DPP4, DPP8 and DPP9 respectively. BMS-767778 exhibits >3,000-fold selectivity over the related enzymes DPP8 and DPP9. BMS-767778 inhibits CYP-3A4 with IC₅₀ of 5.2 μM. BMS-767778 significantly reduces blood glucose levels in high fat fed (HFD) ob/ob mice with safety profile. BMS-767778 can be used for diabetes mellitus research.

DPP8/9-IN-1 (Compound 16) is a selective covalent inhibitor of dipeptidyl peptidases 8 and 9 (DPP8/9) with IC₅₀ values of 14 and 298 nM, respectively. DPP8/9-IN-1 binds irreversibly to the active site serine (S730 in DPP9) via a phosphonate warhead and blocks substrate binding to inhibit DPP8/9-mediated protein processing. DPP8/9-IN-1 is promising for research of cancers and inflammatory diseases.

DPP9-IN-1 (Compound 42) is a dipeptidyl peptidase 9 (DPP9) inhibitor with IC₅₀ of 3 nM for DPP9 and 0.6 μM for DPP8. DPP9-IN-1 induces concentration-dependent LDH release in THP-1 cells.

cis-ICeD-2 is the cis isomer of ICeD-2 (HY-151871). ICeD-2 is a cell death inducer that induces cell death in HIV-1-infected cells. ICeD-2-mediated killing of HIV-1-infected cells is dependent on HIV-1 protease activity. ICeD-2 effectively blocks the hydrolysis of Gly-Pro-AMC by the dipeptidyl peptidases DPP8 and DPP9. ICeD-2 demonstrates strong stability against DPP9 in PBMCs..

DPP8/9-IN-2 (Compound 21) is a DPP8/9 inhibitor with IC₅₀ values of 0.22 nM and 3 nM, respectively, and K_i values of 2.9 nM and 6 nM, respectively . DPP8/9-IN-2 has certain cardiotoxicity, with IC₅₀ values of 0.7 μM, 29.0 μM and 27.7 μM for hERG potassium channel, Nav1.5 sodium channel and Cav1.2 calcium channel, respectively. DPP8/9-IN-2 can be used in the research of diseases such as tumors.
