2-Acetylbutyrolactone Chemical Properties,Usage,Production
Description
It is an important intermediate involved in the synthesis of chemical and pharmaceutical products such as vitamin B, 3,4-substituted pyridine, 5-(2-Hydroxyethyl)-4-methylthiazole. In presence of 2-acetylbutyrolactone, reaction of tert-butyl isocyanide with dialkyl acetylenedicarboxylates leads to the formation of dialkyl (E)-2-{(tert-butylamino)[2-oxo-4,5-dihydro-3(2H)-furanylidene]methyl}-2-butenedioates.1 Moreover, reaction of 2-acetylbutyrolactone with thiosemicarbazide and 3-(2-bromo-acetyl)-chromen-2-one in anhydrous ethanol produced 3-{2-[5-hydroxyl-4-(2-hydroxyl-ethyl)-3-methyl-pyrazol-1-yl]-thiazol-4-yl}-chromen-2-one in good yields.2 In addition, 2-acetylbutyrolactone can also function as the raw material for synthesizing pilocarpine that is a leading therapeutic agent for the treatment of narrow and wide angle glaucoma.3 Besides, this chemical can also act as a fluorogenic reagent in the quantitative spectrofluorometric determination of primary amines, which has been demonstrated to be equally accurate and precise as the officially or other reported methods.4

Biological Activity
ABL1 protooncogene encodes a cytoplasmic and nuclear protein tyrosine kinase th at has been implicated in processes of cell differentiation, cell division, cell adhesion, and stress response. Activity of ABL protein is negatively regulated by its SH3 domain and deletion of the SH3 domain turns ABL1 into an oncogene. Translocation and head-to-tail fusion of the BCR and ABL1 genes is present in many cases of chronic myelogeneous leukemia. The DNA-binding activity of the ubiquitously expressed ABL1 tyrosine kinase is regulated by CDK1-mediated phosphorylation, suggesting a cell cycle function for ABL1.
