Twenty-two quaternary 8-dichloromethylprotoberberine alkaloids were synthesized from unmodified quaternaryprotoberberinealkaloids (QPAs) to improve their physical and chemical properties and to obtain selectively anticancer derivatives. The synthesized derivatives showed more appropriate octanol/water partition coefficients by up to values 3–4 compared to unmodified QPA substrates. In addition, these
