Agents and methods for enhancing recombinant virus transduction in the bladder epithelium are described. A first method involves contacting the luminal surface of the bladder with a composition comprising a transduction enhancing agent and an oncolytic virus. Alternatively, the luminal surface of the bladder can be contacted first with a pretreatment composition comprising a transduction enhancing agent and, subsequently, with a composition comprising an oncolytic virus. Bladder treatment compositions comprising a transduction enhancing agent and an oncolytic virus are also described.

A one-pot reaction of alcohols with trimethylsilyl cyanide and methanesulfonic acid with subsequent neutralization by triethylamine and dehydration by tosyl chloride and pyridine gave the corresponding isocyanides in moderate-to-high yields. This method was used to synthesize tertiary and benzylic isocyanides from the corresponding alcohols. isocyanides -alcohols- Ritter reactions
Electrochemical reduction of alkyl mesylates was successfully carried out by using an undivided cell equipped with a Pt cathode and an Mg anode in the presence of biphenyl and t-BuOH. The reaction could proceed efficiently under mild conditions to give the corresponding alkanes in moderate to good yields. This procedure could also be applicable to chemoselective reduction of mesylates having functional groups such as epoxide, olefin, acetal, hydroxy, or cyano groups.
