Metallocene Antimalarials: The Continuing Quest

Metallocene Antimalarials: The Continuing Quest

Over the last decade, a significant body of research has been developed around the inclusion of a metallocene moiety into known antimalarial compounds. Ferroquine is the most successful of these compounds. Herein, we describe our contribution to metallocene antimalarials. Our approach has sought to introduce diversity sites in the side chain of ferroquine in order to develop a series of ferroqu...

The Continuing Quest for Rationality in Curriculum Practice

Has the leadership role of curriculum workers in instruc tional program planning been usurped by recent trends in back to basics and minimum compe tency testing? Is curriculum devel opment a fait accompli of educa tional funding policies, pressure politics, and legislative mandates? Has the current crisis in education restricted the role and function of curriculum specialists to that of "manage...

Metallocene Based Polyolefin Nanocomposites

One of the most efficient and versatile ways to synthesize polyolefin nanocomposites is the in-situ polymerization of olefins in the presence of nano particles by metallocene catalysts. Metallocene/methylaluminoxane (MAO) catalysts are soluble in hydrocarbons and therefore they can be absorbed perfectly in solution onto the surface of particles or fibers and after addition of ethene or propene ...

9 Titanocene and zirconocene complexes with a phenyl or I-naphthyl substituent in one ,B-position of each Cs-ring ligand and with an interannular tetramethylethanoor dimethylsilano-bridge have been prepared. Racemic complex isomers, which are formed together with varying amounts of their meso isomers, were separated from the latter and characterised by lH NMR spectroscopy and X-ray crystallogra...
