摘要

We report the synthesis and biological properties of novel inhibitors of the Na+, K+-ATPase as positive inotropic compounds. Following our previously described model from which Istaroxime was generated, the 5α, 14α-androstane skeleton was used as a scaffold to study the space around the basic chain of our lead compound. Some compounds demonstrated higher potencies than Istaroxime on the receptor and the (E)-3-[(R)-3-pyrrolidinyl] oxime ...
