摘要:
The present invention is directed to compounds of Formula (I) or pharmaceutically acceptable salts thereof; wherein X is hydrogen, Cl, Br, I, NO2, NR3R4 or —L—Ch; Y is hydrogen, —CH2OR5, —CH2NCH3R1, NO2, NR3R4 or —L—Ch; Y′ is hydrogen, —CH2OH5, —CH2NCH3R1, NO2, NR3R4 OR —L—Ch; provided that at least one of the Y or Y′ is —CH2NCH3R1; Z is S, O, NR6 CR7R8, C(O) or —C(═CR7R8)-; A is hydrogen, Cl, I, Br or —L—Ch; R1 is hydrogen, C1-C5 alkyl, C3-C8 cycloalkyl C1-5 alkylcarbonyl, (C3-C8 cycloalkyl) carbonyl, pnenyl, benzyl, naphthyl, naphthylmethyl or L—Ch; R2 is hydrogen or methyl; and R3-R8 are as defined herein. Radiolabeled compounds of the invention are useful as selective serotonin transporter (SERT) imaging agents for single photon emission tomography (SPECT). As such the compounds are useful for studying the underlying pharmacology and interaction of specific serotinin reuptake site inhibitors (SSRI), commonly used antidepressants, at the SERT sites in the human brain. Certain compounds of the invention, including IDAM (5-iodo-2[[2-2-[(dimethylamino)methyl]phenyl]thio]benzylalcohol) display affinity to SERT sites and show more high selectively for SERT over NET and DAT.
摘要:
The present invention relates to biscarbodiimides, thiourea derivatives, urea derivatives, and cross-linked hyaluronan derivatives having at least one intramolecular disulfide bond, and methods of preparation thereof. The invention also includes thiolated hyaluronan derivatives and salts thereof having at least one pendant thiol group or a modified pendant thiol group, and methods of preparation thereof. An example of a modified pendant thiol group is a sulfhydryl group linked to a small molecule such as a bioactive agent, for example a drug or pharmaceutically active moiety. A hyaluronan derivative having a sulfhydryl group linked to a pharmaceutically active moiety is useful as a sustained or controlled release drug delivery vehicle. Compositions containing the hyaluronan derivatives of the invention can reversibly viscosify in vivo or in vitro, in response to mild changes in condition, and are thus useful in ophthalmic surgery and in tissue engineering.
