Thirty derivates from substituted-phenyl-ethyl methylphosphonates have been synthesized and their inhibiting power of acetyl-cholinesterase have been examined in vitro and in vivo. The correlation between inhibition of the enzyme and electrophylic power of the substituent of the phenyl group was excellent, but when this group contains two substituents, steric factors appear to operate. The acti...

Abstract In vitro culture is not only known for the mass propagation of medicinal plants, it can also be used to boost accumulation useful metabolites. This work was aimed at studying potential elicitation on antioxidant secondary metabolites in different Musa species accessions. Shoot cultures selected six spp. accessions were micropropagated Murashige and Skoog mineral-based medium, supplemen...

The effects of 4-aminopyridine (a non-anticholinesterase antagonist of curare-like agents) on the evoked muscle action potentials (EMAP) in a patient with Eaton Lambert Syndrome are reported. On two separate occasions the i.v. administration of 0.31 mg kg(-1) and 0.62 mg kg(-1) was followed by a 300% increase of EMAP for about 2 h without serious side-effects.
