XIAP Inhibitor

Jolkinolide B is a bioactive diterpene isolated from the roots of Euphorbia fischeriana Steud with oral activity. Jolkinolide B downregulates XIAP, cIAP1, cIAP2, and phosphorylated Akt, upregulates Smac, activates caspase-3 and caspase-9, and inhibits NF-κB, TGFβ/smad3 and JAK/STAT3 pathways. Jolkinolide B exerts comprehensive biological effects including inducing cancer cell apoptosis, suppressing inflammatory responses, improving lung function, alleviating hepatic steatosis and eliminating intracellular Mycobacterium tuberculosis. Jolkinolide B can be used for the research of leukemia, histiocytic lymphoma, asthma, metabolic dysfunction-associated steatotic liver disease and tuberculosis.

Topo I/DDX5-IN-1 (Compound A10) is a Topo I and DDX5 inhibitor. Topo I/DDX5-IN-1 inhibits Topo I activity, binds to DDX5, and suppresses DDX5 function. Topo I/DDX5-IN-1 increases expression of γ-H2AX and p21, suppresses the expression of antiapoptotic proteins (Bcl-2 and XIAP), stimulates ROS generation, and triggers Apoptosis. Topo I/DDX5-IN-1 exhibits anticancer activity against pancreatic cancer, non-small cell lung cancer, skin cancer, and colorectal cancer.

CSLP43 is a selective RIPK2 and XIAP inhibitor with an IC₅₀ of 19.9 nM against human RIPK2. CSLP43 binds to the ATP-binding pocket of RIPK2 and disrupts the interaction between RIPK2 and the BIR2 domain of XIAP or cIAP1. CSLP43 inhibits RIPK2 ubiquitination, NOD1-dependent inflammatory signaling pathways, NOD2-dependent inflammatory signaling pathways, as well as NF-κB activation associated with NOD agonists. CSLP43 is selective for the NOD1/NOD2 signaling pathway and does not inhibit the kinase activity of RIPK1 or RIPK3. CSLP43 is applicable to research related to Crohn's disease, Blau syndrome, early-onset sarcoidosis and early-onset inflammatory bowel disease.

PBX-7016 is a DNA topoisomerase I inhibitor and DDX5 degrader. PBX-7016 induces DNA damage and downregulates Survivin, Mcl-1, and XIAP. PBX-7016 exerts a bystander killing effect. PBX-7016 can serve as an ADC payload for the synthesis of ADC. PBX-7016 is applicable to research related to head and neck cancer, non-small cell lung cancer, breast cancer, colorectal cancer, and ovarian cancer.

CDK9-IN-45 (Compound B11) is a highly selective CDK9 inhibitor with IC₅₀ values for CDK9 and CDK1 of 7.13 and 489.5 nM respectively. CDK9-IN-45 exhibits a potent inhibitory effect on colorectal cancer cells. CDK9-IN-45 induces cell apoptosis and leads to significant accumulation of ROS. CDK9-IN-45 activates Caspase-3, downregulates Mcl-1, XIAP, and c-Myc. CDK9-IN-45 can be used for research on colorectal cancer.

ZLMT-72 is an orally active dual CDK2 and CDK9 inhibitor with IC₅₀s of 0.741 nM and 1.03 nM, respectively. ZLMT-72 shows good selectivity in kinase profiling andcholinesterase inhibition activity. ZLMT-72 has strong antiproliferative effects in the colorectal cancer (CRC) cell line HCT116 (GI₅₀ < 0.1 nM). ZLMT-72 induces apoptosis by inhibiting thephosphorylation of retinoblastoma and RNA polymerase II, resulting in downregulation of antiapoptotic proteins (Mcl-1 and XIAP). ZLMT-72 can be used for the study of colorectal cancer (CRC).

TP-110 is a proteasome inhibitor. TP-110 specifically inhibits the protease-like activity of the 20S proteasome, but does not affect the trypsin-like or peptidyl-glutamyl peptide hydrolysis activity. TP-110 inhibits the NF-κB pathway, activates caspase-8, -9, and -3, and causes PARP cleavage, significantly reducing the levels of cIAP-1 and XIAP. TP-110 causes cell cycle arrest at the G2/M phase and promotes apoptosis of cancer cells. TP-110 can be used in cancer research of prostate cancer and multiple myeloma, etc.

Topoisomerase I inhibitor 17 (Compound 7h) is a Topoisomerase I (Top1) inhibitor. Topoisomerase I inhibitor 17 reduces DDX5 and reverses the locking of Top1 activity by DDX5. Topoisomerase I inhibitor 17 induces Top1-mediated DNA damage and promotes reactive oxygen species (ROS) production. Topoisomerase I inhibitor 17 induces Apoptosis (reduces antiapoptotic proteins XIAP, Bcl-2, Survivin and up-regulates pro-apoptotic proteins Bax, γH2AX). Topoisomerase I inhibitor 17 also blocks the progression of the G2/M checkpoint and induces cell cycle arrest. Topoisomerase I inhibitor 17 significantly inhibits colony formation and cell migration in colorectal cancer cells. Topoisomerase I inhibitor 17 effectively reduces tumors in human PDX tumor mice.

XIAP/cIAP1 antagonist-1 is a potent and orally active XIAP/cIAP1 antagonist with EC₅₀s of 5.1 nM and 0.32 nM for XIAP and cIAP1, respectively. XIAP/cIAP1 antagonist-1 inhibits the tumor growth in dose-dependent manner in vivo.

K882 (Compound 4e) is a Src inhibitor, with K_D of 0.315 μM. K882 induces Apoptosis. K882 inhibits XIAP and Survivin. K882 inhibits the activation of PI3K/Akt/mTOR, Jak1/Stat3, Ras/MAPK signaling pathways. K882 shows anti-tumor activity against non-small cell lung cancer.

T-3256336 is a potent and orally active cIAP1 and XIAP inhibitor with IC₅₀s of 1.3, 200 nM, respectively. T-3256336 shows anti-tumor activity.
