The present invention is directed towards novel compounds that are effective inhibitors of integrins, particularly &agr;IIb&bgr;3 or &agr;v integrins such as &agr;v&bgr;3 and &agr;v&bgr;5. One embodiment of the present invention comprises a compound of formula (I) or formula (II) or a pharmaceutically acceptable salt, solvate, or metabolic precursor thereof. R1, R2, R3, and R4 are defined herein.
摘要:
The present invention comprises a compound of formula I: ##STR1## R.sub.1 of Formula I is substituted amino represented by formula NR.sup.5 R.sup.6 wherein R.sup.5 and R.sup.6 are independently selected from the group consisting of hydrogen, C.sub.1-4 alkyl, and unsubstituted amino with the proviso that R.sup.5 and R.sup.6 are not both hydrogen, and further that R.sup.5 and R.sup.6 are not both amino. R.sub.2 and R.sub.3 of Formula I are independently selected from the group consisting of hydrogen; C.sub.1-4 alkyl; amino; substituted or unsubstituted thiol; and halogen. Moreover, R.sub.4 of Formula I is represented by the formula R.sup.12 -X.sup.12 wherein R.sup.12 is a saturated or unsaturated linear hydrocarbon chain of 5-20 carbons optionally containing one or more interruptions within the chain by a heteroatom, and optionally substituted with one or more .dbd.O, or .dbd.S. Finally, X.sup.12 is selected from the group consisting of hydroxy, an aminoalkyl group, and a known amino acid bound by its .alpha.-amino group.

摘要:
Compounds useful in the treatment of metastatic melanoma and other cancers containing a triazine ring scaffold are described. These compounds may be classified into two groups: (1) two disubstituted triazine rings are covalently linked by an organic linker to each other and (2) one trisubstituted triazine ring.
摘要:
A process for the preparation of metal salts of a medium-chain length monocarboxylic fatty acid comprises reacting the precursor free fatty acid, dissolved in a suitable solvent, with the appropriate metal salt. The process uses a relatively high concentration of free fatty acid as a soluble reactant and produces metal fatty acid salts at high purity and high yield at a reasonable cost.
摘要:
The present invention provides methods for producing linear thiopeptides using an amino acid ortho amino thioanilide compound of formula (III) ##STR1## wherein R.sub.1 is selected from the group consisting of hydrogen or C.sub.1 -C.sub.4 branched or unbranched alkyl;R.sub.2 is selected from the group consisting of hydrogen, halo, amino, hydroxy, C.sub.1 -C.sub.4 branched or unbranched alkoxy, guanido, amido, acyl, carboxy, cyano, mercapto, nitro, azido, and C.sub.1 -C.sub.4 branched or unbranched alkyl optionally substituted by halo, amino, hydroxy, C.sub.1 -C.sub.4 branched or unbranched alkoxy, guanido, amido, acyl, carboxy, cyano, mercapto, nitro, azido;R.sub.3 is a decarboxylated amino acid residue or a decarboxylated amino acid chain comprising at least two amino acid residue.
摘要:

Particular aspects of the invention relate to the use of those salts in the prevention and/or treatment of various diseases and conditions in subjects, including the prevention and treatment of (i) blood disorders, (ii) renal disorders and renal disorder complications; (iii) inflammatory-related diseases; and/or (iv) oxidative stress related disorders.
摘要:
A composition and method for promoting neutrophil survival and activation such as the treatment of neutropenia arising as an undesirable side effect of chemotherapy and radiation therapy. A composition containing medium-chain fatty acids, such as Capri acid or caprylic acid, or salts or triglycerides thereof, or mono- or diglycerides or other analogues thereof or medium-chain triglycerides (MCT) is administered to a human or animal needing treatment in an amount sufficient to reduce or eliminate neutropenia. The composition is administered in an amount effective to treat the disorder. The methods are also useful in the management of bone narrow transplantation and in the treatment of various neutropenic diseases.
