    NMR studies of N-(benzimidazol-2-yl)pyridinium derivatives: QSAR with the anti-leishmanial activity and their carbon-13 NMR chemical shifts
    摘要:
    Quantitative structure-activity - relationships between the in vitro anti-leishmanial activity of N-benzimidazolyl-2,4,6-triphenylpyridinium salts 6 and pyridinium benzimidazolate betaines 7 and their C-13-NMR chemical shifts have been studied, in order to ascertain the influence of the benzimidazole substituents upon anti-leishmanial activity. The calculated C-13-chemical shifts allow the selection of a representative subset of compounds. Several new N-benzimidazolylpyridinium derivatives 6 and 7 have been prepared. Among them, 5-methoxy-1-methylbenzimidazole 21 and 6-methoxy-1-methylbenzimidazole 22 derivatives have high anti-leishmanial activity in vitro and compound 22 shows an interesting activity in vivo although host toxicity is present.

  • [EN] REGIO-SELECTIVE SYNTHESIS OF IMIDAZO[1,2-A]PYRIMIDINES<br/>[FR] SYNTHÈSE RÉGIO-SÉLECTIVE D'IMIDAZO[1,2-A]PYRIMIDINES
    申请人:GENENTECH INC
    公开号:WO2020227576A1
    公开(公告)日:2020-11-12
    A method of regio-selectively synthesizing an imidazo-pyrimidine compound of formulae (XXa) or (XXb) comprising a step of coupling a first compound of formula XX-P1a or XX-P1b with a second compound of formula XX-P2. This annulation reaction between β-ethoxy acrylamides and phosphorylated aminoimidazoles to furnish imidazo[1,2-a]pyrimidin-amines relies on steering effects from endocyclic and exocyclic phosphorylated aminoimidazoles. The reaction furnishes either 2-amino or 4-amino constitutional isomers of imidazo[1,2-a]pyrimidines with good yields and ranges of 90:10 – 99:1 regio-selectivity. The reaction is useful in the synthesis of various tracer molecules used in the study of neurological conditions such as where R3 and R4 together with the imidazole ring atoms to which they are bonded form a phenyl ring and the products are substituted benzimidazopyrimidines. The reaction can be generalized to form imidazo[1,2-a]pyrimidines substituted at either of their 2- and 4- positions by alkoxy or thioalkyl groups.
