Disease relevance of Picoline

• Penclomedine, a synthetic alpha-picoline derivative, was identified as a potential antitumor agent in the P388 leukemia prescreen of the National Cancer Institute. Upon further evaluation in the National Cancer Institute in vivo tumor panel, the compound demonstrated good activity against two breast tumors [1].
• The isolate, identified as an Arthrobacter sp., was capable of utilizing 2-methylpyridine, 2-ethylpyridine, and 2-hydroxypyridine as primary C, N, and energy sources [2].

High impact information on Picoline

• In complex 1, there is an infinite array of six-molecule cycles, based on both hydrogen bonding and pi-pi stacking of the 2-picoline and guanine rings [3].
• Crystalline inclusion complexes between the cyclophane 1 and three isomers of picoline and lutidine were grown and their properties and structures were studied by X-ray analysis, thermal gravimetry (TG), and differential scanning calorimetry (DSC) [4].
• Contrasting chemistry of cis- and trans-platinum(II) diamine anticancer compounds: hydrolysis studies of picoline complexes [5].
• A mixture of 2-methylpyridine, creatinine and aldehydes was heated in diethylene glycol containing 5% water for 1 h at 140 degrees C. The mutagenic compounds were purified by XAD-2 column chromatography, acid/base partition, blue cotton treatment, thin layer chromatography and HPLC [6].
• delta 3-7 alpha-Phenylacetamidodesacetoxycephalosporanic acid was prepared by ring expansion of 6-epi-benzylpenicillin-S-sulfoxide, using N,O-bis(trimethylsilyl)acetamide (BSA) as silylating and dehydrating agent and alpha-picoline/alpha-picoline hydrobromide as catalyst [7].

Associations of Picoline with other chemical compounds

• When provided with 2-methylpyridine, 2-ethylpyridine, and 2-hydroxypyridine simultaneously, 2-hydroxypyridine was rapidly and preferentially degraded; however there was no apparent biodegradation of either 2-methylpyridine or 2-ethylpyridine until after a seven day lag [2].
