Mutated EGFR-IN-1 (Osimertinib analog) is a useful intermediate for the inhibitors design for mutated EGFR, such as L858R EGFR, Exonl9 deletion activating mutant and T790M resistance mutant.

Mutated EGFR-IN-2 (compound 91) is a mutant-selective EGFR inhibitor extracted from patent WO2017036263A1, which potently inhibits single-mutant EGFR (T790M) and double-mutant EGFR (including L858R/T790M (IC50=＜1nM) and ex19del/T790M), and can suppress activity of single gain-of-function mutant EGFR (including L858R and ex19del) as well. Mutated EGFR-IN-2 shows anti-tumor antivity.

A multi-kinase inhibitor

RTC-5 (TRC-382) is an optimized phenothiazine with anti-cancer potency. RTC-5 demonstrates efficacy against a xenograft model of an EGFR driven cancer, its effects is attributed to concomitant negative regulation of PI3K-AKT and RAS-ERK signaling.

Ruxolitinib sulfate (INCB018424 sulfate) is the first potent, selective JAK1/2 inhibitor to enter the clinic with IC50s of 3.3 nM/2.8 nM, and has > 130-fold selectivity for JAK1/2 versus JAK3.

A Pim-1 kinase inhibitor

STAT3-IN-1 is a potent, selective, and orally active inhibitor of STAT3 with IC 50 values of 1.82μM and 2.14μM in HT29 and MDA-MB-231 cells, respectively.

STAT3-IN-3 is a potent and selective inhibitor of signal transducer and activator of transcription 3 (STAT3), with anti-proliferative activity. STAT3-IN-3 induces apoptosis in breast cancer cells. STAT3-IN-3 acts as a promising mitochondria-targeting STAT3 inhibitor for cancer research.

Tyk2-IN-7 (Compound 48) is a TYK2 JH2 inhibitor, binds to TYK2 JH2 domain with IC50 and Ki.

Tyk2-IN-8 (Compound 3) is a selective Tyk-2 inhibitor with an IC50 of 5.7 nM for TYK2-JH2.

WHI-P180 (Janex 3) is a multi-kinase inhibitor; inhibits RET, KDR and EGFR with IC50s of 5 nM, 66 nM and 4 μM, respectively.

ZM39923 is a JAK3 inhibitor, with a pIC50 of 7.1; ZM39923 also potently inhibits tissue transglutaminase (TGM2) with an IC50 of 10 nM.

Beta-hydroxyisovalerylshikonin is a natural product isolated from Lithospermium radix, acts as a potent inhibitor of protein tyrosine kinases (PTK), with IC50s of 0.7μM and 1μM for EGFR and v-Src receptor, respectively. Beta-hydroxyisovalerylshikonin is effective against a wide variety of tumor cell lines, and most efficiently induces cell-death in NCI-H522 and DMS114 cells.

Theliatinib (Xiliertinib) is a potent, ATP-competitive, orally active and highly selective EGFR inhibitor with a Ki of 0.05 nM and an IC50 of 3 nM. Theliatinib has an IC50 of 22 nM for EGFR T790M/L858R mutant. Theliatinib shows >50-fold selectivity for EGFR than other kinases. Anti-tumor activity.

Tyrphostin AG30 (AG30) is a potent and selective EGFR tyrosine kinase inhibitor. Tyrphostin AG30 (AG30) selectively inhibits self renewal induction by c-ErbB, and is able to inhibit activation of STAT5 by c-ErbB in primary erythroblasts.
