Description:	DFHO is a fluorogenic ligand of Corn fluorogenic aptamer. The RNA aptamer, Corn binds DFHO with a Kd value of 70 nM and converts it to a fluorescent form, enabling RNA imaging in cells.
Target:	Kd: 70 nM (Corn binds DFHO)[1]
In Vitro:	Corn is tested in E. coli. Minimal fluorescence that is seen in DFHO-treated cells (20 μM) transformed with the empty vector. However robust yellow fluorescence is seen in E. coli expressing Corn[1]. Corn-DFHO exhibits markedly enhanced photostability in vitro. The Corn-DFHO complexes are imaged in mammalian cells. Since the U6 promoter is one of the three major Pol III promoters, Corn from the U6 promoter is expressed and replaced the majority of the U6 sequence with Corn, leaving a minimal 5′ capping element leader sequence. The majority of the cells expressed diffuse yellow fluorescence, most prominently in the cytoplasm)[1]. DFHO exhibits low background fluorescence and cytotoxicity, making it a potentially suitable fluorophore for activation by RNA aptamers and for imaging experiments in living cells[2].

Cat. No.	Product name	Field of application
DC31074	Isopropyl myristate	Isopropyl myristate is the ester of isopropyl alcohol and myristic acid.
DC79609	NCGC00685960	NCGC00685960 is a Nicotinamide N-methyltransferase (NNMT) inhibitor with an IC50 < 10  nM. NCGC00685960 has potent antitumor activity. NCGC00685960 increases H3K27 trimethylation levels in ovarian cancer cells and inhibits α-SMA expression in NNMT-expressing ovarian fibroblasts. NCGC00685960 reduces 1-MNA levels, reverses SAM and H3K27 hypomethylation and significantly impairs collagen contractility in cancer-associated fibroblasts (CAFs). NCGC00685960 can be used for cancers research.
DC77813	Zeltociclib	Zeltociclib is a cyclin-dependent kinase inhibitor with antitumor effects.
DC77714	S3226	S3226 is an inhibitor for Na+/H+ exchange subtype 3 (NHE3) with an IC50 of 0.2 µmol/L in rat NHE3 transfected fibroblasts. S3226 exhibits protective activity in rat ischemia-induced acute renal failure models.
DC75868	AZ14133346	AZ14133346 (compound 36) is a potent and selective inhibitor of EGFR Exon20 insertions, with the IC50 of 85 nM. AZ14133346 plays an important role in cancer research.
DC75865	TI17	TI17 represents a novel class of targeted anticancer agents that specifically disrupt DNA damage repair mechanisms in malignant cells.
DC75816	Nisoxetine	Nisoxetine acts as a highly selective and potent noradrenaline transporter (NET) antagonist, exhibiting a binding affinity (Kd) of 0.76 nM. In addition to its antidepressant properties, nisoxetine functions as a local anesthetic by inhibiting voltage-gated sodium channels. This dual pharmacological activity makes it a compound of interest for both neurological and pain management research.
DC75641	GENZ-644282 TFA salt	Genz-644282, also known as SAR402674, is a non-camptothecin inhibitor of topoisomerase I with potential antineoplastic activity. Topoisomerase I inhibitor Genz-644282 binds to and inhibits the enzyme topoisomerase I, which may result in the inhibition of repair of single-strand DNA breaks, DNA replication, and tumor cell growth in susceptible tumor cell populations.
DC75325	PSMA-617 TFA	PSMA-617, also know as vipivotide tetraxetan, is a ligand used to make 177Lu-PSMA-617, which is a radioactive molecule to fight cancer. PSMA617 possesses a small peptide, which was designed to target prostate-specific membrane antigen (PSMA). PSMA617 demonstrates high radiolytic stability for at least 72 h. PSMA617 has high inhibition potency (equilibrium dissociation constant Ki=2.34±2.94 nM on LNCaP; Ki=0.37±0.21 nM enzymatically determined). 177 Lu-PSMA-617 offers a potential additional life-prolonging treatment option for men with mCRPC.
