TASK DEFINITION: Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.
PROBLEM: A novel Ca2+/calmodulin-dependent protein kinase II (CaM Kinase II) inhibitor, KN-93 potently inhibits gastric acid secretion from parietal cells. As previously reported (1), treatment of parietal cells with a selective inhibitor of CaM kinase II, KN-62 resulted in the inhibition of cholinergic-stimulated rabbit parietal cell secretion, whereas it failed to inhibit the histamine and forskolin response. In contrast effects of carbachol, histamine and forskolin were significantly inhibited by KN-93 with an IC50 of 0.15, 0.3 and 1 microM, respectively; these effects occurred without any changes in intracellular cyclic AMP and Ca2+ levels. In the present study we investigated the mechanism by which KN-93 acts upon the acid-secreting machinery of gastric parietal cells. Neither redistribution of the proton pump activity nor the morphological transformation were affected by KN-93. The drug only weakly inhibited the H+, K(+)-ATPase activity but strongly dissipated the proton gradient formed in the gastric membrane vesicles and reduced the volume of luminal space. Thus KN-93 acts at pH gradient formation whereas KN-62 acts only at CaM Kinase II.

SOLUTION: Which kinase is inhibited by the small molecule KN-93?

PROBLEM: Riociguat (Adempas(®)), an oral first-in-class soluble guanylate cyclase (sGC) stimulator, is under global development by Bayer Healthcare Pharmaceuticals Inc. for the treatment of adult patients with inoperable or chronic/persistent chronic thromboembolic pulmonary hypertension (CTEPH) and for the treatment of adult patients with pulmonary arterial hypertension (PAH). The drug directly stimulates sGC in a nitric oxide independent manner, thereby increasing the sensitivity of sGC to nitric oxide, leading to increased cyclic guanosine monophosphate generation (a key signalling molecule involved in regulating vascular tone, proliferation, fibrosis and inflammation). Riociguat is the world's first approved pharmacotherapy for CTEPH, with its first global approval in this indication occurring in Canada. It has subsequently been approved in the USA for the treatment of patients with CTEPH and also received its first global approval in patients with PAH in the USA. It is undergoing regulatory review for these indications in Europe and for use in patients with CTEPH in Japan. This article summarizes the milestones in the development of riociguat, leading to its first global approvals in patients with CTEPH and PAH.

SOLUTION: What is generic name of drug Adempas?

PROBLEM: By 1971, Cortez was wrestling in America and held the AWA World Tag Team Championship with Red Bastien On July 24, 1971, Hercules Cortez died of injuries suffered in a one-car accident near St. Cloud, Minnesota early in the morning.

SOLUTION:
Was the death of Hercules Cortez an accident or suicide?
