摘要:
Orally nonabsorbed or poorly absorbed drugs may be converted to orally absorbed prodrug derivatives by derivatization of free functional groups selected from amino, hydroxyl, mercapto, phosphate and/or carboxyl with groups sensitive to mild basic conditions such as 9-fluorenylmethoxycarbonyl (Fmoc), 2-sulfo-9-fluorenylmethoxycarbonyl (Fms), and fluorenylmethyl (Fm).
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:
Reversible pegylated drugs are provided by derivatization of free functional groups of the drug selected from amino, hydroxyl, mercapto, phosphate and/or carboxyl with groups sensitive to mild basic conditions such as 9-fluorenylmethoxycarbonyl (Fmoc) or 2-sulfo-9-fluorenylmethoxycarbonyl (FMS), to which group a PEG moiety is attached. In these pegylated drugs, the PEG moiety and the drug residue are not linked directly to each other, but rather both residues are linked to different positions of the scaffold Fmoc or FMS structure that is highly sensitive to bases and is removable under physiological conditions. The drugs are preferably drugs containing an amino group, most preferably peptides and proteins of low or medium molecular weight. Similar molecules are provided wherein a protein carrier or another polymer carrier replaces the PEG moiety.
摘要:
The present invention relates to pharmaceutical compositions for the treatment of female sexual dysfunction, for vaginal relaxation and/or for modulation of sperm motility. The composition comprises as active ingredient (i) a peptide analogue or conjugate of vasoactive intestinal peptide (VIP) as defined in the specification and is preferably formulated for topical application in the vaginal, vulvar and/or clitorial area. The invention also relates to the use of the VIP peptide analogue or conjugate for the preparation of a pharmaceutical composition for the treatment of female sexual dysfunction, for vaginal relaxation and/or for modulation of sperm motility. Yet further, the invention provides a method of treatment of female sexual dysfunctions and/or vaginal relaxation by the use of said peptide analogue and/or conjugate.
摘要:
A process for producing reagents useful in organic synthesis, for removing metal values from solutions thereof, for the capture of aldehydes, of the general formula ##STR1## wherein Z designates a recurring part (CH.sub.2 --CH--CH.sub.2) of a polymeric backbone of a polymer like polystyrene, of a copolymer comprising polystyrene and divinylbenzene, and butadiene, or other copolymers comprising styrene moieties; or wherein Z is the aliphatic moiety of a long-chain aralkyl compound having a terminal aryl group; or wherein Z designates alkyl; corresponding compounds wherein instead of the optionally substituted phenyl group there is present an optionally substituted naphthyl group; wherein n is an integer of from 1 to 15, and wherein Q designates a group selected from: ##STR2## wherein R designates --H, lower alkyl, aryl, which may be substituted and wherein R" designates --H, alkyl, aryl, halogen, nitro or carboxy, or ##STR3## wherein R is --H, lower alkyl, aryl (which may be substituted), R.sub.1 is --H, alkyl, aryl (which may be substituted), R.sub.2 is --H, alkyl, aryl or substituted aryl, and wherein Y is --H or a non-interferring substituent, which comprises chemically binding an activated chemical moiety to a group ##STR4## or a corresponding naphthyl-containing group, wherein Z is as defined above, according to the reaction scheme: ##STR5## wherein Q is as defined above, or a functional group which can be converted to such group after the chemical bonding; and X is --Cl or --Br.
