Largazole

(別名: (+)-Largazole)

Largazole ((+)-Largazole) is an orally active, blood-brain barrier-permeable class I histone deacetylase (HDAC) inhibitor with in vivo anticancer activity and osteogenic efficacy. As a prodrug, Largazole hydrolyzes to Largazole thiol (HY-170890), which has a K_i value of 0.07 nM against human HDAC2. Largazole regulates the cell cycle, induces apoptosis, upregulates tumor suppressors and osteoblast differentiation markers, inhibits osteoclast formation, and upregulates neuroprotection-related genes. Largazole can be used in the research of various cancers including colorectal cancer, as well as neurodegenerative diseases.

体外実験

Largazole is a prodrug, with potency against HDAC1 approximately 10-fold lower than that of its active metabolite Largazole thiol (HY-170890) and potency against HDAC6 two orders of magnitude lower; Largazole potently inhibits human class I HDAC subtypes HDAC1, HDAC2, and HDAC3, with K_i values of 20 nM, 21 nM, and 48 nM, respectively; Largazole thiol potently inhibits purified human HDAC2, with a K_i value of 0.07 nM^[1]^[2]^[3].
Largazole induces acetylation of histone H3 (Lys9/14) in HCT116 colon cancer cells at nanomolar low concentrations, but does not alter the acetylation level of α-tubulin (Lys40) even at concentrations as high as 10 μM, which reflects its selective inhibitory activity against class I HDACs^[1].
Largazole dose-dependently induces osteoblast differentiation by upregulating Runx2 and BMPs, while inhibiting osteoclast formation, exhibiting dual activities of stimulating bone formation and suppressing bone resorption^[1].
Largazole (0.3 μM; 12 h) increases the expression level of the BDNF gene by 1.4-fold in SF-268 glioblastoma cells^[2].
Largazole inhibits the growth of various cancer cell lines at nanomolar concentrations, while exhibiting significantly lower inhibitory activity against non-transformed epithelial cells and fibroblasts, demonstrating selective targeting of transformed cells^[1].
Largazole (incubated for 48 h) potently inhibits the proliferation of SF-268 and SF-295 glioblastoma (GBM) cells with IC₅₀ values of 62 nM and 68 nM, respectively; it also potently inhibits the proliferation of SH-SY5Y neuroblastoma cells with an IC₅₀ value of 102 nM^[2].
Largazole potently inhibits the growth of transformed human MDA-MB-231, U2OS, HT29, and IMR-32 cells (GI₅₀ values 7.7 nM, 55 nM, 12 nM, and 16 nM, respectively), and exhibits selective activity relative to untransformed NMuMG and NIH3T3 cells; it also potently inhibits the proliferation of cultured human malignant melanoma cell lines in vitro^[3]^[4].
Largazole induces cell cycle arrest (G1 phase arrest at 3 nM, G2/M phase arrest at concentrations >30 nM) and triggers apoptosis at concentrations >30 nM by regulating cell cycle inhibitors, CDKs/cyclins, and pro-apoptotic BCL2 family proteins in HCT116 colon cancer cells and NB4 leukemia cells^[1].

体内実験

Largazole (i.p.) demonstrates in vivo anticancer activity in HCT116 colon cancer xenografts by downregulating IRS-1 and compromising IGF signaling, with no observed acute toxicity^[1].
Largazole (local implantation via collagen sponge) induces in vivo woven bone formation in a mouse calvarial bone formation model when delivered via collagen sponge implantation^[1].
Largazole (local application via MBCPs) enhances in vivo bone fracture healing in a rabbit calvarial model when combined with MBCPs, promoting direct contact bone formation^[1].
Largazole (5-200 mg/kg; i.p.; p.o.; single dose; daily; 4 consecutive days) crosses the blood-brain barrier in healthy mice, achieves therapeutically relevant brain concentrations of its active form Largazole thiol, upregulates neuroprotective genes including Bdnf, Pax6, and Oprm1, and predicts beneficial effects on nervous system function while exhibiting low acute and repeated-dose toxicity^[2].

Induced pronounced brain histone hyperacetylation after 4 hours at 50 mg/kg single i.p..
Resulted in brain largazole thiol concentrations of ~300 nM after 4 hours, decreasing to ~80 nM after 24 hours at 50 mg/kg single i.p..
Resulted in brain largazole thiol concentrations near the in vitro GBM IC₅₀ after 4 hours at 10 mg/kg single i.p. or 50 mg/kg single p.o..
Resulted in a 3.3-fold increase in brain Bdnf gene expression 12 hours post-administration at 50 mg/kg single i.p..
Identified 1220 differentially expressed genes (≥2.5-fold change, p < 0.05), including a 3.0-fold increase in Pax6 and 4.6-fold increase in Oprm1 gene expression after single i.p. dose of 50 mg/kg.
Predicted increased activation of nervous system functions (including neurogenesis, neuron development, neurite growth, cognition, and learning) and decreased activation of neurological diseases (including movement disorders, seizure disorders, ataxia, and congenital brain malformations) after single i.p. dose of 50 mg/kg.
Was well tolerated at single i.p. doses up to 200 mg/kg.
Caused no toxicity with repeated i.p. dosing of 60 mg/kg or 75 mg/kg for 4 consecutive days.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
