生物活性

L002 is a potent, cell permeable, reversible and specific acetyltransferase p300 (KAT3B) inhibitor with an IC50 of 1.98 μM. L002 binds the acetyl-CoA pocket and competitively inhibits the FATp300 catalytic domain, blocks histone acetylation and p53 acetylation, and inhibits STAT3 activation. L002 has the potential for hypertension‐induced cardiac hypertrophy and fibrogenesis treatment.

体外研究

L002 also has weak inhibitory effects against PCAF and GCN5 (IC50s =35 and 34 µM, respectively) and is specific for p300 over a panel of additional acetyltransferases, deacetylases, and methyltransferases.

体内研究

L002 (intraperitoneal injection; 20 μg/gm body weight; every 3rd day; 2 weeks) reverses hypertension‐induced cardiac hypertrophy and fibrosis by treatment of mice after inducing hypertension for two weeks significantly.It also reduces the levels of perivascular and interstitial collagen in the myocardium compared to non-treated hypertensive mice.

Animal Model: Wild‐type C57BL/6 male mice planted with osmotic minipumps ( Angiotensin II 1500 ng/kg/min) for 4 weeks
Dosage: 20 μg/gm body weight; every 3rd day; 2 weeks
Administration: Intraperitoneal injection
Result: Reversed hypertension-induced cardiac fibrosis in mice.

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% saline

    Solubility: ≥ 2.08 mg/mL (6.47 mM); Clear solution

    此方案可获得 ≥ 2.08 mg/mL (6.47 mM,饱和度未知) 的澄清溶液。

    以 1 mL 工作液为例,取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;向上述体系中加入50 μL Tween-80,混合均匀;然后继续加入 450 μL生理盐水定容至 1 mL。

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
