This invention relates to 3-(4-acrylamidobenzoyl)benzo�b! thiophenes, to the process for their preparation, to pharmaceutical compositions and to their use for modifying the balance between bone resorption and bone production in a mammal. The compounds useful in this invention are represented by the formula ##STR1## wherein R.sup.1 and R.sup.2 are independently hydrogen or lower alkyl containing 1-8 carbon atoms, or R.sup.1 and R.sup.2 together with the interposed nitrogen forms a 5-7 membered ring optionally containing an additional heteroatom selected from nitrogen, sulfur or oxygen.

This invention relates to 4-phenoxy (and 4-substituted phenoxy)5-hydroxy-2(5H)-furanones of the formula: ##STR1## where Z is ##STR2## where R is H, halogen, C.sub.1 -C.sub.8 alkyl, C.sub.3 -C.sub.8 cycloalkyl, trifluoromethyl, or ##STR3## and X is H, C.sub.1 -C.sub.8 alkyl, --O--C.sub.1 -C.sub.8 alkyl, or halogen; a process for their preparation, their use in the treatment of osteoporosis, and pharmaceutical compositions thereof.

Inhibition of bone loss by 4-aryloxy-5-hydroxy-2(5H)-furanones

This invention relates to 4-substituted-5-hydroxy-2(5H)-furanones, to the process for their preparation, to pharmaceutical compositions containing said 4-substituted-5-hydroxy-2(5H)-furanones and to the use of said 4-substituted-5-hydroxy-2(5H)-furanones for modifying the balance between bone production and bone resorption in a host animal, including man.
