(1) trans--CH.dbd.CH--,

(2) cis--CH.dbd.CH--,

(3) --C.tbd.C--, or

(4) --CH.sub.2 CH.sub.2 --;

wherein R.sub.3 is

(a) alkyl of one to 12 carbon atoms, inclusive,

(b) cycloalkyl of 3 to 10 carbon atoms, inclusive,

(c) aralkyl of 7 to 12 carbon atoms, inclusive,

(d) phenyl,

(e) phenyl substituted with one, 2 or 3 chloro or alkyl of one to 4 carbon atoms, inclusive;

(f) p-[(p-acetamido)benzamido]phenyl,

(g) p-(benzamido)phenyl,

(h) p-(acetamido)phenyl,

(i) --(p--Ph)--NH--CO--NH.sub.2, wherein (p-Ph) is para-phenyl,

(j) --(p(Ph)--CH.dbd.N--NH--C.dbd.O--NH.sub.2, wherein (p-Ph) is as defined above,

(k) .beta.-naphthyl,

(l) --CH(R.sub.11)--CO--R.sub.10

wherein R.sub.10 is phenyl, p-bromophenyl, p-biphenylyl, p-nitrophenyl, p-benzamidophenyl, or 2-naphthyl; wherein R.sub.11 is hydrogen or benzoyl;

(m) hydrogen; or

(n) a pharmacologically acceptable cation.

With regard to the divalent substituents described above, e.g., Q and W.sub.1, these divalent radicals are defind as .alpha.-R.sub.i :.beta.-R.sub.j where R.sub.i represents a substituent of the divalent moiety of the alpha configuration with respect to the cyclopentane ring and R.sub.j represents a substituent of the divalent moiety of the beta configuration with respect to the cyclopentane ring. Accordingly, when Q is defined as .alpha.-OH:.beta.-R.sub.8, the hydroxy of the Q moiety is in the alpha configuration, i.e. as in prostacyclin, and the R.sub.8 substituent is in the beta configuration. Not all carbon atoms to which such divalent moieties are attached represent asymmetric centers. For example, when both valence bonds are to hydrogen, (e.g., W.sub.1 or Q is .alpha.-H:.beta.-H), then no asymmetric center is present.
