The present invention is directed to compounds of the general formula I and pharmaceutically acceptable salts thereof: ##STR1## wherein R=H or lower alkyl; R'=H, lower alkyl, benzyl, CH.sub.2 OH; A=(CH.sub.2).sub.1 to 5, >C(CH.sub.3).sub.2, >C (CH.sub.2).sub.3 ; and X=0 or 1. The present invention is also directed to a method of treating a person for sickle cell anemia comprising administering to the person a therapeutically effective dosage of the above compounds. In addition the invention includes the novel compound: ##STR2## which is inaccessible by synthetic procedures previously described for this general class of compounds.

In search of a drug to treat sickle cell anemia, several analogues of the diuretic ethacrynicacid (ECA) have been synthesized and found equivalent in antigelling potency to ECA, but they have moderate or little diuretic activity. Structure-activity studies revealed that most of the highly active derivatives contain an acryloyl moiety. The latter functionality reacts covalently with protein sulfhydryl
