Dragonrend wouldn't work on a vampire as presumably they were mortal at one point and know what mortality is. Well, it is not daedrarend, and as it doesn't work on lesser daedra who can die to an extent and reform in the waters of Oblivion, a prince is not going to be phased, even Peryite. Malacath experienced soul recycling by force, so he'd be completely fine.

Akatosh might be sent reeling, but it would likely be only a short stagger stun like how certain dragons will only land for a split second before taking back off. The other divines might be considerably less so, considering draconic is not their language.

Deities who have definitively experienced death such as Tsun (The whalebone bridge might be his corpse!) would be completely fine knowledge of draconic aside, as they already felt mortality if only for that sleeping instant before awaking in the godly realm or Nirn or wherever.
