Descrição geral

Caffeine Mettler-Toledo melting point standard is useful for the routine calibration of Mettler-Toledo melting point instrument. The value for its melting point equals an average of 6 to 12 measurements with a Mettler-Toledo MP70 excellence melting point instrument that is calibrated with primary standards.

Aplicação

Mettler-Toledo calibration standard ME 18872, caffeine (234-236.5 °C) finds its use in the calibration of thermosystem 900, in both pharmacopeia and thermodynamic modes of operation.
This mp standard is also employed as a temperature calibration standard in thermal analysis techniques.

Ações bioquímicas/fisiológicas

Estimulante do sistema nervoso central que se acredita agir por meio de receptores de adenosina e neurotransmissores monoamina. É um antagonista do receptor de adenosina e inibidor da adenosina 3′,5′-monofosfato cíclico (cAMP) fosfodiesterase. Assim os níveis de cAMP aumentam nas células após o tratamento com cafeína. Relata-se que afeta os níveis celulares de cálcio, liberando o cálcio de depósitos intracelulares. Ela cancela os efeitos no ciclo celular de diversas substâncias químicas, como os inibidores de protease, impedindo a apoptose; demonstrou-se que isso inibe os mecanismos celulares de reparo do DNA.
