生物活性
JNJ-10229570 (UNII-N9IX402L35) is is a novel melanocortin receptor 1 (MC1R) and melanocortin receptor 5 (MC5R) antagonist, which inhibits the binding of 125I-NDP-α-MSH to cells expressing human MC1R and MC5R with IC50 values of 270 nM and 200 nM, respectively. JNJ-10229570 dose dependently inhibits the production of sebaceous lipids in cultured primary human sebocytes.
In vivo, topical treatment with JNJ-10229570 of human skins transplanted onto SCID mice result in a marked decrease in sebum-specific lipid production, sebaceous gland's size and the expression of the sebaceous differentiation marker epithelial-membrane antigen (EMA). Topical treatment with 0.05% JNJ-10229570 leads to a distinct reduction in both the steady-state and the newly-synthesized sebum-specific lipids, with lesser effects on triglycerides and cholesterol.

| 方法 |
Nile red assay. Briefly, differentiated sebocytes grown in 96-well plates were treated with or without 1 uM of JNJ-10229570 (8 repeats, 8 days), washed once, incubated in 1 uM Nile red and 0.001% Pluronic F127 (4 h, RT, dark), and washed again. Fluorescence (485 nm excitation, 565 nm emission) was determined in a SPECTRAmax Gemini-EM plate reader (Molecular Devices, Sunnyvale, CA) by SoftMax Pro program. |

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
