The present invention relates to useful diterpenes and pharmaceutical compositions containing them of the formula:
for use in the treatment of cardiovascular and inflammatory diseases and for cancers susceptible to an NF-κB inhibitor and an endothelin receptor inhibitor. The present invention also relates to compounds and methods useful to inhibit cell proliferation and for the induction of apoptosis.
A concise and efficient approach was established for the divergent totalsynthesis of (±)-tanshindiol B and C and tanshinone I from a ubiquitous ene intermediate in 1–2 steps. This critical intermediate was derived from (±)-tanshinol B, which was synthesized in 50% overall yield over 3 steps using an ultrasound-promoted cycloaddition as a key step. Compared to a previously reported strategy, our approach
