CH5164840 is a potent and selective HSP90 inhibitor. CH5164840 showed remarkable antitumor activity against NSCLC cell lines and xenograft models. CH5164840 has potent antitumor activity and is highly effective in combination with erlotinib against NSCLC tumors with EGFR overexpression and mutations.

Azumolene sodium anhydrous is a muscle relaxant that inhibits the release of calcium from skeletal muscle sarcoplasmic reticulum. Azumolene inhibits a component of store-operated calcium entry coupled to the skeletal muscle ryanodine receptor. Azumolene, an equipotent dantrolene analog, inhibits a component of SOCE coupled to activation of RyR1 by caffeine and ryanodine, whereas the SOCE component induced by thapsigargin is not affected.
