摘要:
The present invention provides a long chain fatty acid (LCFA)-like albumin-binding probe/ligand containing no hydrolysable bond and having an enhanced associating affinity with human serum albumin, which upon conjugation with an amino- or mercapto-containing short-lived drug and administration of the conjugate, significantly prolongs the life time of said drug without substantially interfering with its pharmacological activity. The invention further provides conjugates of said probe with amino- or mercapto-containing drugs, as well as pharmaceutical compositions and uses thereof.

摘要:
Disclosed are salts of nucleoside analogs and methods of forming the salts. An anion of a nucleoside analog is paired with a permanent counter cation to form a salt that has decreased melting point and increased aqueous solubility compared to the nucleoside compound prior to the salt formation. Also a cation of a nucleoside analog is paired with a permanent counter anion to form a salt that has decreased melting point and increased aqueous solubility compared to the nucleoside compound prior to the salt formation. The nucleoside analog in some embodiments has therapeutic activity such as antiviral. The permanent counter cation or anion in some embodiments has bioactivity such as antibacterial or being a vitamin.

摘要:
Sulfonate compositions are disclosed. The compositions include alkanesulfonates, alkenesulfonates, sultones, and hydroxy-substituted alkanesulfonates. The sulfonates comprise a reaction product of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives with a sulfonating or sulfitating agent. In one aspect, the sulfonate composition is a sulfo-estolide made by reacting a metathesis-derived C10-C17 monounsaturated acid or octadecene-1,18-dioic acid with a sulfonating agent, optionally in the presence of a saturated fatty acid. The sulfonates are valuable for a wide variety of end uses, including cleaners, fabric treatment, hair conditioning, personal care (liquid cleansing products, conditioning bars, oral care products), paint additives, antimicrobial compositions, agricultural uses, and oil field applications.
