DOUBLE STRANDED OLIGONUCLEOTIDE CONSTRUCT COMPRISING ANDROGEN RECEPTOR SPECIFIC SEQUENCE, AND COMPOSITION FOR PREVENTING HAIR LOSS AND PROMOTING HAIR GROWTH COMPRISING SAME

Disclosed are a double stranded oligonucleotide construct, configured such that a hydrophilic material and a hydrophobic material are conjugated through a simple covalent bond or a linker-mediated covalent bond to both ends of a double stranded oligonucleotide in order to efficiently deliver an androgen-receptor-specific oligonucleotide into a cell, a nanoparticle capable of being produced by self-assembling double stranded oligonucleotide constructs in an aqueous solution through hydrophobic interactions, and a composition for preventing hair loss or promoting hair growth containing the double stranded oligonucleotide construct. The double stranded oligonucleotide construct including the androgen-receptor-specific oligonucleotide and the composition for preventing hair loss or promoting hair growth containing the same as an active ingredient can suppress the expression of an androgen receptor with high efficiency without side effects, and can thus exhibit excellent effects on preventing hair loss, particularly androgenetic alopecia, alopecia areata, and telogen effluvium, and promoting hair growth.

Cleavable conjugates of catechol compounds and water-soluble polymers and methods of treatment using the same

Described are conjugates comprising a water-soluble polymer linked to a compound comprising a catechol moiety via a cleavable linkage, wherein the cleavable linkage is formed between the water-soluble polymer and a first phenolic hydroxyl group of the catechol moiety and a second phenolic hydroxyl group of the catechol moiety is linked to a blocking group wherein the rate of hydrolytic release of the compound comprising the catechol moiety is controlled, at least in part, through structure or design of the blocking group on the second phenolic hydroxyl group of the catechol moiety. Therefore, the rate of hydrolytic release of the compound comprising the catechol moiety can be tuned through structural design of the group on the second phenolic hydroxyl group of the catechol moiety. Compounds used in the synthesis of the described conjugates and methods of using the described conjugate and other compounds in the treatment of dopamine-responsive disorders are also described.
