DNA methyltransferases (DNMTs) are responsible for DNA methylation, an epigenetic modification involved in gene regulation. Families of conjugates of procainamide, an inhibitor of DNMT1, were conceived and produced by rapid synthetic pathways. Six compounds resulted in potent inhibitors of the murine catalytic Dnmt3A/3L complex and of human DNMT1, at least 50 times greater than that of the pare...
An 82-year-old female, with left femoral neck fracture was scheduled for left hip hemiarthroplasty, under spinal anaesthesia. She had been suffering from diabetes, hypertension, lung cancer and was previously treated with IV aminophylline for respiratory insufficiency. She was given spinal anaesthesia with 10 mg of 0.5% hyperbaric bupivacaine, and T6 sensory block level was established. After 1...
A patient who developed a multisystem involvement of systemic lupus erythematosus (SLE) after 9 years of procainamide therapy, during which time he ingested enormous amounts of the drug, is described. The patient first suffered from recurrent episodes of pleuritis and arthritis, after which he developed a characteristic SLE nephritis associated with a high level of antinative DNA antibodies and...
Procainamide, a type 1A antiarrhythmic drug, blocks sodium channels and reduces the maximum rate of rise of the cardiac action potential (Vmax) in a rate-dependent fashion. In vitro, the magnitude of this rate-dependent reduction in Vmax is greater in tissue that is partially depolarized at rest than in tissue with a normal resting potential. Reductions in Vmax produced by drugs that block sodi...
