The Design and Synthesis of Novel Phenothiazine Derivatives as Potential Cytotoxic Agents Abstract Background: Cancer incidence and mortality have been increasing and cancer is still the leading cause of death all over the world. Despite the enormous progress in cancer treatment, many patients died of ineffective chemotherapy and drug resistance As an alternative or even an adjunct to quinacrine therapy, phenothiazine derivatives effective in PrP Sc inhibition may be used to treat humans, despite their weaker antiprion potency in our ScN2a cell assay, because they may cross the BBB more effectively. It will be important to treat patients dying of prion diseases within the context of well designed clinical trials to establish as rapidly as possible whether quinacrine or phenothiazine derivatives can provide effective treatment مشتقات الفينوثيازين Phenothiazine derivatives تستخدم المركنات sedation بشكل واسع في الطب البيطري من أجل التحكم بالحيوانات ولإنجاز بعض الفحوص الطبية أو العمليات الجراحية سواء بالمشاركة الدوائية أو مع التسكين analgesia الموضعي أو في بدء التبنيج premedication مع المخدرات العامة Phenothiazine derivatives are neuroleptic drugs used in the treatment of schizophrenia and anxiety.
