Description:	Risdiplam is an orally administered, centrally and peripherally distributed SMN2 pre-mRNA splicing modifier that increases survival motor neuron (SMN) protein levels.
Target:	SMN2
In Vitro:	Risdiplam modulates SMN2 pre-mRNA splicing towards the production of full-length SMN2 mRNA and increases SMN protein levels. Risdiplam is a modifier of SMN2 splicing, leading to an increase in SMN2 full length transcript and thus functional SMN protein. Spinal muscular atrophy (SMA) type I remains the most common genetic disease resulting in death in infancy. Characterized by progressive motor and respiratory muscle weakness, this autosomal recessive neuromuscular disorder is caused by low levels of the survival motor neuron protein (SMN) due to inactivating bi-allelic deletions and other disabling mutations in the survival motor neuron 1 (SMN1) gene[1].

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.
DC77831	Vicadrostat	Vicadrostat (compound 29 A) is a potent and selective inhibitor of aldosterone synthase(CYP11B2) with an IC50 of 16 nM. It exhibits potential in renal disease, diabetic nephropathy, cardiovascular diseases and fibrotic disorder 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.
DC77387	AUR1545	AUR1545 is a selective degrader of KAT2A and KAT2B. AUR1545 can be used in the cancer research, including studies on AML (Acute myeloid leukemia), SCLC (Small-cell carcinoma), and NEPC (Neuroendocrine Prostate Cancer).
DC77822	JNJ-77242113 (Icotrokinr)	Icotrokinra (JNJ-77242113, JNJ-2113, PN-235) is an orally available and selective antagonist of the IL-23 receptor. It also inhibits IL-23–induced STAT3 phosphorylation in peripheral blood mononuclear cells with an IC50 of 5.6 pM and suppresses IL-23–induced IFN-γ production in NK cells with an IC50 of 18.4 pM. It also exhibits anti-inflammatory activity in a TNBS-induced colitis model in rats and holds potential for studying psoriasis, psoriatic arthritis, and inflammatory bowel disease.
DC77088	T025	T025 is as an orally available and potent inhibitor of Cdc2‐like kinases (CLKs) with an IC50s of 0.93 nM, 1 nM, 14 nM, 1.5 nM for CLK1, CLK2, CLK3, DYRK1B respectively. It exhibits anti‐tumor efficacy and can be used in MYC‐driven cancer research.
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.
