A new study on terphenyl and diaryl-isoxazole and -isoxazoline derivatives, maintaining a common 3-adamantyl-4-hydroxyphenyl moiety, has been conducted to find compounds with growth supporting and antiapoptotic properties. Unexpectedly, diphenyisoxazole derivatives bearing a nitro group replacing the carboxylic function have been found with the highest cell protective activity within the series, in complete and in serum-free conditions. Inhibition of apoptosis induced by daunorubicin has also been observed for the most active compound.
Studies on the apoptotic activity of natural and synthetic retinoids: Discovery of a new class of synthetic terphenyls that potently support cell growth and inhibit apoptosis in neuronal and HL-60 cells

New terphenyl derivatives have been synthesized and tested for their effect on cell survival in serum-free cultures. These compounds protected HL60 cells from death and supported their growth with an activity higher than that of the natural 14-hydroxy-retro-retinol. Terphenyls 26 and 28 also possess antiapoptotic activity on neuronal cells, proving them as possible candidates for the treatment of neurodegenerative and ischemic diseases.

A double Suzuki cross-coupling protocol has been devised as a practical route to a variety of terphenyls. Good chemoselectivity was observed. Unsymmetrically substituted triphenylenes were also easily prepared.

Second-order rate constants have been measured for the saponification of methyl 2'-, 3'-, and 4'-substituted biphenyl-4-carboxylates at several temperatures in 85percent (w/w) methanol-water and activation parameters have been calculated.The Hammett equation applies very well to the saponification of 3'- and 4'-substituted biphenyl-4-carboxylates with ?-constants evaluated by the FMMF method.The effect of 2'-substituents is understandable in terms of ?-electron steric effects.
