Sarmustine (SarCNU) is an alkylating agent with anticancer activity that inhibits the growth of prostate cancer cells via p53-dependent and p53-independent pathways.Sarmustine mediates the selection of P140K methylguanine-DNA-methyltransferase-transduced human CD34(+) cells in vitro.

CDKI-73 is a potent CDK9 inhibitor (Ki: 4 nM). It shows selective toxicity to CLL cells(LD50=80 nM) versus normal B cell and normal CD34+ cell(LD50>20 uM).The inhibition of CDK9 induces apoptosis and potentiates the effect of cisplatin.

OAC1 (BAS 00287861) is a compound activating Octamer-binding transcription factor 4 (Oct4). It enhances the iPSC reprogramming efficiency and accelerates the reprogramming process.

Purinostat is a selective inhibitor of HDACI IIb with potential anti-leukemic properties. Its mesylate form, Purinostat mesylate, is effective at inhibiting the survival of Ph+ leukemic cells and CD34+ leukemic cells derived from CML patients. Purinostat mesylate targets HDACI IIb, impacting several crucial factors for leukemia stem cell (LSC) survival, such as c-Myc, β-Catenin, E2f, Ezh2, Alox5, and mTOR. Additionally, Purinostat mesylate enhances glutamate metabolism in LSCs by increasing GLS1.

StemRegenin 1 is an aryl hydrocarbon receptor signaling antagonist (IC50: 127 nM in CD34+ cells).

Debio 0617B is a multi-kinase inhibitor that reduces maintenance and self-renewal of primary human AML CD34+ stem progenitor cells. debio 0617B targets key kinases upstream of STAT3 STAT5 signalling, such as JAK, ABL, SRC and class III V receptor tyrosine kinases. debio 0617B can be used to study STAT3 driven solid tumours.

MEISi-1 is a novel MEIS inhibitor (MEISi), significantly inhibiting MEIS-luciferase reporters in vitro and inducing murine (LSKCD34low cells) and human (CD34+, CD133+, and ALDHhi cells) HSC self-renewal ex vivo.

PHA-680626 is a potent and selective PLK inhibitor. PHA-680626 exhibits anti-proliferative and pro-apoptotic activity on Imatinib-resistant chronic myeloid leukemia cell lines and primary CD34+ cells by inhibition of both Bcr-Abl tyrosine kinase and Aurora kinases. PHA-680626 inhibits Plk1 (IC50 = 0.53 μM), Plk2 (IC50 = 0.07 μM) and Plk3 (IC50 = 1.61 μM).

BAY-364 (BAY-299N) functions as an inhibitor targeting the second bromine domain in TAF1, demonstrating inhibitory effects on TAF1 in Kasumi-1 cells, CD34+ cells, and K562 cells with respective IC50 values of 1.0 µM, 10.4 µM, and 10.0 µM.

EPI-X4, an endogenous peptide fragment of human serum albumin (amino acids 408-423), serves as an antagonist to the chemokine (C-X-C motif) receptor 4 (CXCR4). It effectively prevents calcium mobilization and receptor internalization triggered by chemokine (C-X-C motif) ligand 12 (CXCL12) in HEK293 cells with CXCR4 expression, at concentrations between 0.8 and 1,000 µM. Moreover, EPI-X4 hampers the CXCL12-driven migration of both Jurkat T cells and human CD34+ hematopoietic stem cells. In an acute allergic airway hypereosinophilia mouse model, EPI-X4 intrinsically decreases Cxcr4-dependent inflammatory cell infiltration in airways at a dose of 16 µmol/kg. Additionally, increased urinary EPI-X4 levels, inversely related to glomerular filtration rate (GFR), are observed in chronic kidney disease patients, indicating its potential biomarker role.
