LR-90 is an advanced glycation end product (AGE) inhibitor, inhibits inflammatory responses in human monocytes[1]. LR-90 is also used in the research of diabetic animal model[2].
LR-90 (0, 25, 50, 100, and 200 μM) inhibits RAGE, MCP-1, COX-2, IP-10 and NOX2 mRNA expression in THP-1 cells in a dose-dependent manner, after pretreatment 1 h befor S100b stimulatation for 4 hours[1].LR-90 (0, 25, 50, 100, and 200 μM) dose-dependently and significantly blocks THP-1 cells adherence to endothelial cells after pretreatment 1 h befor S100b stimulatation for 24 hours[1].LR-90 (0, 25, 50, 100, and 200 μM, for 24 hours) shows no effect on the cell viability of THP-1 cells[1].|| Cell Viability Assay[1]||Cell Line:|THP-1 cells|Concentration:|0, 25, 50, 100, and 200 μM|Incubation Time:|24 hours|Result:|Showed no cytotoxicity to THP-1 cells.|| RT-PCR[1]||Cell Line:|THP-1 cells|Concentration:|0, 25, 50, 100, and 200 μM|Incubation Time:|One hour before S100b addition for 4 hours|Result:|Dose-dependently inhibited mRNA expression of RAGE, MCP-1, COX-2, IP-10, and NOX2 stimulated with S100b.
LR-90 (50 mg/L, p.o. for 27 weeks) significantly reduces plasma lipids, modestly affects hyperglycaemia in ZDF rats[2].LR-90 (50 mg/L) decreases renal AGE, AGER and lipid peroxidation[2].|| Animal Model:|Male ZDF rats (13 to 40 weeks)[2]|Dosage:|50 mg/L|Administration:|P.O. for 27 weeks|Result:|Significantly reduced plasma triacylglycerol and cholesterol by ∼55% and ∼30%, respectively. Modestly affected hyperglycaemia and blood pressure. Lowered the body weight.

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
