Isomerism in the Chemistry of Organogermanium Compounds (Part II)

The organogermanium chemistry covers huge fields, as shown by a survey covering the crystallographic and structural data of over four hundred and fifty examples. Over 10 percent of those compounds exist as distortion isomers (around 97 %) and ligand isomers (around 3 %). These are discussed in term of coordination around the Ge(II), Ge(IV) and Ge2 +3 atoms, and correlations are drawn between do...

Preparation of the Phencyclidine Analogues (Part II)

Using a-tetralone, as starting material, a series of phencyclidine analogues were synthesized. This ketone was reacted separately with ethylmagnesium bromide, P-methoxyphenylmagnesium bromide and P-methylphenylmagnesium bromide. The resultant alcohols were treated with a suspension of NaN3 and CCl3COOH in CHCl3. The azides were subsequently...

Anticancer Natural Compounds: Molecular Mechanisms and Functions 
Part II

In spite of enormous success achieved by the cancer biologists and clinical oncologists alike for the last decades, cancers still presents a great challenge for the researchers and suffering for the patients. While basic mechanisms underlying tumor initiation and progression are unraveling as we speak, as well as novel therapeutic strategies often appear in clinical practice the tumors defend t...
