Ki: 0.22 μM (Hck)[1]
Hck (hematopoietic cell kinase), a Src family tyrosine kinase. iHCK-37 is a specific Hck inhibitor with a Ki of 0.22 uM. It binds to the ATP-binding pocket of Hck, blocking its kinase activity and downstream signaling pathways including PI3K/AKT and MAPK/ERK. |
|---|---|
| ln Vitro |
iHCK-37 (5.0 -20 μM; 24 hours) displays strong in vitro antiproliferative action. Growth inhibitory (GI50) values (μM) are 5.0-5.8 μM for AML cell lines (HL60, KG1a and U937) and 9.1-19.2 μM for chronic myelogenous leukemia cell lines (HEL and K562) [2]. iHCK-37 (3-9 μM; plus erythropoietin) results in reduced ERK, AKT, and P70S6K phosphorylation in lentivirally HCK-silenced K562 and U937 cell lines [2]. iHCK-37 (3-9 μM) causes a dose-dependent reduction in p-HCK, p-ERK, p-AKT, and p-70S6 in the cell line KG1a (AML/CD34+) [2].
iHCK-37 inhibits Hck with a Ki of 0.22 uM, making it a potent and specific Hck inhibitor. iHCK-37 blocks HIV-1 viral replication with an EC50 of 12.9 uM. In high Hck-expressing cells, iHCK-37 reduces PI3K/AKT and MAPK/ERK pathway activation after erythropoietin induction. It has been shown to have antitumor activity, likely through inhibition of Hck-mediated survival signaling in CML cells. |
| ln Vivo |
iHCK-37 has been studied for its ability to block HIV-1 viral replication. It reduces PI3K/AKT and MAPK/ERK pathway activation in high Hck-expressing cells, which may have implications for CML research. However, no detailed in vivo efficacy data are reported. It is primarily used as a research tool for in vitro studies of Hck function.
|
| Enzyme Assay |
Cell-free Hck kinase activity assays are performed using recombinant human Hck enzyme. The enzyme is incubated with a peptide substrate and ATP in the presence of increasing concentrations of iHCK-37 (0.001-10,000 nM) in assay buffer (50 mM HEPES, pH 7.5, 10 mM MgCl2, 1 mM DTT). After 30-60 min at 30degC, the reaction is terminated, and Ki (0.22 uM) is determined by measuring phosphorylated substrate via luminescence (ADP-Glo) or 33P incorporation. Selectivity is assessed against other Src family kinases (e.g., Src, Lyn, Fyn) and unrelated kinases.

| Cell Assay |
Cell Viability Assay[1]
Cell Types: U937, HL60, KG1a, HEL and K562 cells Tested Concentrations: 5.0-20 μM Incubation Duration: 24 hrs (hours) Experimental Results: demonstrated a reduction of growth in a dose-dependent manner. High Hck-expressing cell lines (e.g., certain CML cell lines) are seeded and treated with iHCK-37 at various concentrations (0.1-100 uM) for 24-72 hours. For Hck target engagement, cells are stimulated with erythropoietin (EPO) to activate Hck in the presence or absence of iHCK-37, and downstream signaling (PI3K/AKT, MAPK/ERK) is assessed by Western blot. For HIV-1 replication assays, HIV-1-infected cells are treated with iHCK-37, and viral replication is measured by p24 ELISA or qRT-PCR. Cell viability is assessed by MTT assay. EC50 for HIV-1 inhibition (12.9 uM) is determined. |
| Animal Protocol |
No specific in vivo animal protocols are published for iHCK-37. For potential in vivo studies, iHCK-37 would be formulated in a suitable vehicle (e.g., 10% DMSO + 40% PEG300 + 5% Tween-80 + 45% saline) and administered to mice by intraperitoneal injection or oral gavage. For HIV-1 studies, humanized mice or transgenic mouse models would be used. For CML studies, xenograft models with Hck-expressing CML cells could be used. Efficacy would be assessed by tumor volume measurement, viral load, or pathway inhibition. No such studies are reported.
