DMH2 is a novel and potent antagonist of bone morphogenetic protein (BMP) type I receptor with Ki values of <1, 5.4 and 43 nM for ALK6, ALK3 and ALK2, respectively. It caused a decrease in cell growth and apoptosis of H1299 non-small cell lung carcinoma cells in vitro.

Biological Activity
| ln Vitro | Three lung cancer cell lines with K-Ras mutations (A549, H157, H727) and three lung cancer cell lines without K-Ras mutations (H1299, H865, U1752) exhibit growth impairment due to reduced expression of Id1 and Id3. Display[1]. The combination of DMH2 and PP2 significantly reduced Id1 promoter activity and inhibited growth in A549 cells more than either drug did alone [1]. |
| ln Vivo | At a dosage of 2 mg/kg, DMH2 (0–2 mg/kg, IP, twice daily, 2 days prior to PH (partial hepatectomy), 2 days subsequent to PH) enhanced hepatocyte proliferation from 13.7% to 26.9% [2]. |
| Animal Protocol |
Animal/Disease Models: C57BL/6 mice (7-8 weeks, male) [2] Doses: 0.5, 1, 2 mg/kg Route of Administration: IP twice (two times) daily, 2 days before PH, 2 days after PH (partial Hepatectomy) Experimental Results: Hepatocyte proliferation increased from 13.7% to 26.9% at the 2 mg/kg dose. |

Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
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 (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *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)] *Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

Oral Formulation 3: Dissolved in PEG400 Oral Formulation 4: Suspend in 0.2% Carboxymethyl cellulose Oral Formulation 5: Dissolve in 0.25% Tween 80 and 0.5% Carboxymethyl cellulose Oral Formulation 6: Mixing with food powders Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently. (Please use freshly prepared in vivo formulations for optimal results.) |
