Lp-PLA2-IN-5 is a potent inhibitor of lipoprotein-associated phospholipase A2 (Lp-PLA2). Lp-PLA2 previously known as platelet- activating factor acetylhydrolase (PAF-AH), is a phospholipase A2 enzyme involved in hydrolysis of lipoprotein lipids or phospholipids. Lp-PLA2-IN-5 has the potential for the research of diseases associated with the activity of Lp-PLA2, for example atherosclerosis, Alzheimer's disease (extracted from patent WO2021228159A1, compound 32)[1].
Quinacrine is a fluorescent probe for the conformational transitions of the cholinergic receptor protein. Quinacrine shows activity in the low μM range with a mean IC50 of 2.30 μM In the patient AML cells.IC50 value: 2.30 μM (for AML cells)Target:in vitro: Quinacrine is a fluorescent probe for the conformational transitions of the cholinergic receptor protein in its membrane-bound state.[1] In the patient AML samples, Quinacrine showed activity in the low μM range with a mean IC50 of 2.30 μM, statistically significantly lower than that of normal PBMCs; 3.54 μM (P=0.0327; Student's t-test). Samples from patients with chronic lymphocytic, acute myeloid and lymphocytic leukemias as well as peripheral blood mononuclear cells (PBMC) were tested in response to 1266 compounds from the LOPAC1280 library. 25 compounds were defined as hits with activity in all leukemia subgroups (<50% cell survival compared with control) at 10 μM drug concentration. Only Quinacrine showed concurrent high activity in all leukemia subgroups and low activity in normal PBMCs and was, therefore, selected for further preclinical evaluation. Quinacrine also induced early inhibition of both DNA and protein synthesis. Quinacrine have repositioning potential for treatment of acute myeloid leukemia by targeting of ribosomal biogenesis.[2]
