Excitatory postsynaptic currents (EPSCs), miniature excitatory postsynaptic currents (MEPSCs), and acetylcholine-induced current fluctuations (noise) have been studied in voltage-clamped bullfrog parasympathetic ganglion cells of the atrial septum. EPSCs were also recorded from voltage-clamped sympathetic B cells and, in general, it

The development of miniature end-plate currents (m.e.p.c.s) was studied in the superior oblique and interhyoideus muscles of Xenopus laevis. An analysis of m.e.p.c. decays shows that each muscle possesses its own characteristic programme of end-plate current development. In the superior

The treatment of morphinan 1 with NaH and MsCl provided very stable iminium salt 7 possessing propellane skeleton. One of the synthesized iminium salts 7, isobutyl derivative 7b, was crystallized and its structure was determined by X-ray crystallography. The natural

A new series of 8-chloro-5,5-dioxoimidazo[1,2-b][1,4,2]benzodithiazine derivatives 8-25 with heteroaryloxycarbonyl or heteroarylcarbamoyl substituents at position 7 have been synthesized as potential antitumor agents. In this procedure a novel type of mixed anhydride 7 was prepared from 8-chloro-5,5-dioxoimidazo[1,2-b][1,4,2]benzodithiazine-7-carboxylic acid 6 and methanesulfonyl

Continuing search for beneficial additive toward the Beckmann rearrangement (BR) of indanone oxime has revealed that common Lewis acid catalyst in methanesulfonyl chloride (MsCl) showed increasing efficiency in this ionic rearrangement. The new protocol with MsCl is superior to the
