Compound 2 (20–40 µM; 0-144 hours; BE(2)–C, SK–N–BE(2), and SH–SY5Y cells) treatment resulted in a concentration-dependent reduction in the number of cells Quantity[2]. Compound 2 (1-naphthohydroxamic acid) at concentrations that grew neurite-like structures that stained positive for neurofilaments and decreased cell density within the range of its in vitro IC50 against HDAC8. 1. In soft tissues, naphthohydroxamic acid inhibits the formation of colonies. Dependence of Agar concentration [2]. Only tubulin became hyperacetylated when 1-naphthalene hydroxamic acid (Compound 2; 0.8 µM, 4 µM, 20 µM, or 100 µM) was applied to either kind of cell (HeLa or HEK293 cells)[1].

Compound 2 (0–40 mg/kg; intraperitoneal; daily; for 10 days; NMRI Foxn1 nude mice) exhibited dose-limiting toxicities (DLT) that included weight loss and indicators of hepatotoxicity, such as increased liver examination histology and the detection of necrotic regions in plasma liver enzymes. 50 mg/kg of 1-naphthalene hydroxamic acid per day is the highest dose that can be tolerated. Neither blood parameters nor body weight are significantly changed at these amounts [3]. Pharmacokinetic analyses conducted following intraperitoneal injection of the inhibitor revealed that 1-naphthalene hydroxamic acid has a half-life of roughly 15 minutes and a peak plasma concentration of about 30 μM [3].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
