Compositions and methods for treating bone deficit conditions
First Claim
1. A method to treat a condition in a vertebrate animal characterized by a deficiency in, or need for, bone growth replacement and/or an undesirable level of bone resorption, which method comprises administering to a vertebrate subject in need of such treatment an effective amount of a compound of the formula:
-
space="preserve" listing-type="equation">Ar.sup.1 --L--Ar.sup.2wherein Ar1 has the formula;
##STR42## wherein Ra is a non-interfering substituent;
m is an integer of 0-4;
each dotted line represents an optional π
-bond;
each Z is independently N, NR, O, S, CR or CR2, where each R is independently H or alkyl (1-6C);
X is O, S, SO or SO2 ;
L is a flexible linker; and
Ar2 is a substituted or unsubstituted 6-membered aromatic ring.

Abstract
Compounds containing two aromatic systems covalently linked through a linker containing one or more atoms, or "linker" defined as including a covalent bond per se so as to space the aromatic systems at a distance 1.5-15 Å, are effective in treating conditions associated with bone deficits. The compounds can be administered to vertebrate subjects alone or in combination with additional agents that promote bone growth or that inhibit bone resorption. They can be screened for activity prior to administration by assessing their ability to effect the transcription of a reporter gene coupled to a promoter associated with a bone morphogenetic protein and/or their ability to stimulate calvarial growth in model animal systems.
