Diaryl-substituted ortho-carboranes 1 were synthesized from the corresponding alkynes by decaborane coupling under microwave-irradiated conditions with a combination of N,N-dimethylaniline and chlorobenzene. Among the compounds synthesized, 1a and 1d exhibited significant inhibition of hypoxia-induced HIF-1 transcriptional activity. Both compounds similarly suppressed hypoxia-induced HIF-1α accumulation in a concentration-dependent manner without affecting HIF-1α mRNA expression.
