COH34 1 Publications Verification	Poly(ADP-ribose) Glycohydrolase (PARG)	Cancer
COH34 is a potent and specific poly(ADP-ribose) glycohydrolase (PARG) inhibitor with an IC₅₀ of 0.37 nM. COH34 binds to the catalytic domain of PARG (K_d=0.547 μM), thereby prolonging PARylation at DNA lesions and trapping DNA repair factors .

HY-N6726

Fumonisin B3	Fungal Endogenous Metabolite	Infection Cancer
Fumonisin B3 is an orally active fumonisin Mycotoxin. Fumonisin B3 can be isolated from Fusarium moniliforme, Fusarium proliferatum and Fusarium nygamai. Fumonisin B3 induces precancerous lesions, triggers embryonic death of chicken embryos, causes severe hemorrhage in dead chicken embryos. Fumonisin B3 can be used in studies related to hepatocellular carcinoma .

HY-E70577

Endonuclease IV	Endonuclease	Others
DNA repair enzyme. Endonuclease IV has endonuclease activity at AP sites, 3' phosphodiesterase activity that can remove a variety of ligation-blocking lesions from the 3' end of DNA, endonuclease activity on oxidative DNA lesions, and 3' to 5' exonuclease activity .

HY-164496

KL-50	DNA/RNA Synthesis	Cancer
KL-50 is a selective toxin toward tumors that lack the DNA repair protein O ⁶-methylguanine-DNA-methyltransferase (MGMT), which reverses the formation of O ⁶-alkylguanine lesions. KL-50 activates DNA damage response pathways and cycle arrest in MGMT-cells, independent of mismatch repair (MMR). KL-50 is promising for research of brain tumors that lack the DNA repair protein MGMT .

HY-175812

MU876	Endonuclease	Cancer
MU876 (Compound 32) is a MUS81 inhibitor with an IC₅₀ of 0.5  μM. MU876 effectively inhibits MUS81-dependent homologous recombination (HR) and break-induced replication (BIR) pathways. MU876 sensitizes cancer cells to DNA-damaging agents, such as Cisplatin (HY-17394), through impairing their ability to repair DNA lesions. MU876 can be used for cancers chemotherapy research .

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
