Publication:	1. Jason G. Kettle, et al. AACR Abstract 979: Discovery of the JAK1 selective kinase inhibitor AZD4205. 2. Patent: WO 2017050938 A1 20170330, Example 32.

Description:	AZD-4205 is a selective JAK1 inhibitor, with an IC50 of 73 nM, weakly inhibits JAK2, and shows little inhibition on JAK3 (IC50, >14.7, >30 μM, respectively).
Target:	JAK1:73 nM (IC50)
In Vivo:	AZD-4205 (12.5 mg/kg BID (twice daily), 25 m/kg BID or 50 mg/kg BID, p.o.) alone has increasing antitumor effects, and ehances the antitumor activity of osimertinib, compared to treatment with osimertinib alone in mice bearing NCI-H1975 cells[1].
In Vitro:	AZD-4205 (Example 32) is a selective JAK1 inhibitor, with an IC50 of 73 nM, weakly inhibits JAK2, and shows little inhibition on JAK3 (IC50, >14.7, >30 μM, respectively). AZD-4205 significantly inhibits STAT3 phosphorylation in NCI-H 1975 cells with an IC50 of 161 nM[1].

Cat. No.	Product name	Field of application
DC31074	Isopropyl myristate	Isopropyl myristate is the ester of isopropyl alcohol and myristic acid.
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.
DC75202	Fosaprepitant free acid	Fosaprepitant, also known as MK0517, is an antiemetic drug, administered intravenously. It is a prodrug of aprepitant. Fosaprepitant was developed by Merck & Co. and was approved. It is a prodrug of Aprepitant. It aids in the prevention of acute and delayed nausea and vomiting associated with chemotherapy treatment. Fosaprepitant is a weak inhibitor of CYP3A4, and aprepitant, the active moiety, is a substrate, inhibitor, and inducer of CYP3A4
DC74748	O4I4	O4I4 (compound 23) is a OCT4-inducing compound with metabolical stability.
DC74684	ZH8667	ZH8667 is a trace amine-associated receptor 1 (TAAR1)–Gs agonist.
DC74646	EB-PSMA-617	EB-PSMA-617 is an Evans blue-modified prostate-specific membrane antigen (PSMA) 617 ligand for making 177Lu-EB-PSMA, which is potential useful for Metastatic Castration-Resistant Prostate Cancer.
