Gem-dialkyl-7-oxabicycloheptane substituted prostaglandin analogs useful in treating thrombotic and vasospastic disease have the structural formula
wherein m is 1, 2 or 3; n is 0, 1, 2, 3 or 4;
Z is -(CH₂)₂-, -CH=CH- or
with the proviso when Z is -CH=CH-, n is l, 2, 3 or 4; R is CO₂H, CO₂lower alkyl, or CO₂alkali metal, X is O or NH; and where R¹ and R² are as defined herein and R³ and R⁴ are each independently alkyl, or R³ and R⁴ may be taken together with the carbon to which it is attached to form a 3- or 4-membered ring.
Gem-二烷基-7-氧杂双环庚烷基取代前列腺素类似物在治疗血栓性和血管痉挛性疾病方面有用,其结构式为m为1、2或3;n为0、1、2、3或4;Z为-(CH₂)₂-,-CH=CH-或者在Z为-CH=CH-时,n为1、2、3或4;R为CO₂H、CO₂较低烷基,或CO₂碱金属,X为O或NH;其中R¹和R²如上所定义,R³和R⁴各自独立为烷基,或R³和R⁴可以与其附着的碳一起形成3-或4-成员环。
