It also inhibits PDE III and PDE IV while significantly activating Epac, demonstrating diverse pharmacological activities [1] [2].

Rp-8-CPT-cAMP is a structural combination of the lipophilic and non-hydrolyzable cAMP analogs, 8-CPT-cyclic AMP and Rp-cyclic AMPS .[1] It functions as a site-selective inhibitor of protein kinase A (PKA) type I and II, with preference towards site A of type I and site B of type II.2 By occupying cAMP binding sites at the regulatory subunit of PKA, Rp-8-CPT-cAMP prevents the kinase holoenzyme from dissociative activation.[2],[3]

Sp-8-CPT-cAMPS is a powerful and specific cAMP analog that activates cAMP-dependent protein kinase A (PKA I and PKA II) selectively and effectively. It exhibits a 153-fold preference for site A of RI over site A of RII, and a 59-fold preference for site B of RII over site B of RI.

Rp-8-CPT-cAMPS is a powerful and competitive antagonist of cAMP-induced activation of cAMP-dependent protein kinase (PKA) I and II. Acting as a potent cAMP analog, Rp-8-CPT-cAMPS exhibits a preference for site A of RI over site A of RII. Additionally, it favors site B of RII over site B of RI. This compound effectively inhibits cAMP-dependent PKA activation and demonstrates selectivity in binding to specific sites within the protein kinase.

CPT-157633 is a difluoro-phosphonomethyl phenylalanine derivative that acts as a potent inhibitor of the enzyme PTP1B. It effectively prevents the development of glucose intolerance induced by binge drinking.

CU-CPT9b (TLR8-specific antagonist 1) is an antagonist of toll-like receptor 8 (TLR8; Kd = 21 nM). It inhibits activation of NF- B induced by the TLR8 agonist R-848 in TLR8-overexpressing HEK-Blue cells with an IC50 value of 0.7 nM.

CU-CPT-9a is a potent TLR8 inhibitor (IC50 : 0.5 nM), that suppresses TLR8-mediated proinflammatory signaling in various cell lines and human primary cells-

CU-CPT-8m (TLR8-specific antagonist) is an toll-like receptor 8 (TLR8) antagonist (IC50 : 67 nM)

8-Cyclopentyl-1,3-dimethylxanthine (CPT) is a potent antagonist of adenosine A1 receptor.

McN3716 is a carnitine palmitoyltransferase I (CPT-1) inhibitor used for researching metabolic diseases.

TLR3-IN-1 (CU CPT 4a) is a selective TLR3 inhibitor (IC50: 3.44 μM in RAW 264.7 cells). It can inhibit TLR3/dsRNA complex-mediated downstream signaling pathways and inhibit the production of TNF-α and IL-1β in whole cells.

9-Oxononanoic Acid is an oxidized fatty acid, formed by the autoxidation of linoleic acid, which enhances phospholipase A2 (PLA2) activity and increases the production of thromboxane B2 in isolated human plasma.9-Oxononanoic Acid reduces hepatic neofatty acid synthesis and enhances the activity of rat hepatic carnitine palmitoyltransferase, a marker of β-oxidation. Activity.

9-amino-CPT (Aminocamptothecin) is an inhibitor of topoisomerase I with potent anticancer activity.

Camptothecin (CPT) belongs to the alkaloid group of natural products and is a specific DNA topoisomerase I (Topo I) inhibitor (IC50=679 nM) with specificity. Camptothecin has antitumor activity and induces apoptosis.

Irinotecan hydrochloride trihydrate (CPT-11 HCl Trihydrate) keeps DNA from unwinding by inhibiting topoisomerase 1.

Irinotecan Hydrochloride (CPT-11 hydrochloride) is the hydrochloride salt of a semisynthetic derivative of camptothecin. Irinotecan, a prodrug, is converted to a biologically active metabolite 7-ethyl-10-hydroxy-camptothecin (SN-38) by a carboxylesterase-converting enzyme. One thousand-fold more potent than its parent compound irinotecan, SN-38 inhibits topoisomerase I activity by stabilizing the cleavable complex between topoisomerase I and DNA, resulting in DNA breaks that inhibit DNA replication and trigger apoptotic cell death. Because ongoing DNA synthesis is necessary for irinotecan to exert its cytotoxic effects, it is classified as an S-phase-specific agent.

Irinotecan (CPT-11), a derivative of camptothecin, is an inhibitor of DNA topoisomerase I (Topo I). Irinotecan has antitumor activity by preventing DNA strand reattachment through binding to the Topo I complex, resulting in double-stranded DNA breaks and cell death.

Perhexiline maleate is an orally active inhibitor of CPT1 and CPT2, reducing fatty acid metabolism, with IC50 values of 77 μM and 148 μM against rat heart and liver CPT1, respectively.

Etomoxir sodium salt ((R)-Etomoxir sodium salt) is a carnitine palmitoyltransferase 1a (CPT-1a) inhibitor that inhibits fatty acid oxidation (FAO). Etomoxir sodium salt has antitumor activity.

iRGD–CPT is an iRGD-camptothecin conjugate covalently linked via a heterobifunctional linker. It exhibits anticancer activity both in vivo and in vitro and can be utilized in colon cancer research.

(GalNAc)3-CPT is a glycan-conjugated prodrug that targets the asialoglycoprotein receptor (ASGR) overexpressed on liver cells. It demonstrates significant antitumor activity by activating the cGAS-STING pathway and promoting CD8+ T cell infiltration into tumor sites, leading to apoptosis of tumor cells. In HepG2 cells, it shows an IC50 value of 3.07 μM.

CPT-Se3, a camptothecin (CPT) seleno-derivative, exhibits enhanced anticancer efficacy by effectively killing cancer cells and hindering tumor proliferation. This compound diminishes the GSH/GSSG ratio and total thiols while increasing ROS levels, ultimately triggering apoptosis in Hep G2 cells. Furthermore, CPT-Se3 demonstrates significant cytotoxicity against HeLa, Hep G2, A549, and SMMC-7721 cell lines with IC50 values ranging from 2.19 to 4.7 μM [1].
