Abstract:
PURPOSE: A manufacturing method of (S)-dapoxetine hydrochloride is provided to manufacture the (S)-dapoxetine hydrochloride in high yield rate with relatively short processing steps which are 6 steps in total by using a regioselective and stereoselective introduction of an amine group with using chlorosulfonylisocyanate. CONSTITUTION: A manufacturing method of (S)-dapoxetine hydrochloride comprises: a step of manufacturing (S)-3-chloro-1-phenylpropane-1-ol by reacting 3-chloro-1-phenylpropan-1-one with diethylanilineborane; a step manufacturing (S)-(1-(benzyloxy)-3-chloropropyl) benzene by reacting the (S)-3-chloro-1-phenylpropane-1-ol with benzyl bromide; a step of manufacturing (S)-benzyl 3-chloro-1-phenylpropylcarbamate by reacting the (S)-(1-(benzyloxy)-3-chloropropyl) benzene with chlorosulfonyl isocyanate; a step of manufacturing (S)-benzyl 3-(naphthalene-1-yloxy)-1-phenylpropyl carbamate by reacting the (S) -benzyl 3-chloro-1-phenylpropylcarbamate with naphthalen-1-ol (S); a step manufacturing (S)-3-(naphthalene-1-yloxy)-1-phenylpropan-1-amine by hydrogenate reacting the (S)-benzyl 3-(naphthalene-1-yloxy)-1-phenylpropyl carbamate; a step of manufacturing (S)-dapoxetine hydrochloride by reacting the (S)-3-(naphthalene-1-yloxy)-1-phenylpropan-1-amine with formic acid and formaldehyde.
Abstract:
PURPOSE: A composition for anti-allergy including (1R,2R,3R)-3-amino cyclopentane -1,2- diol is provided to suppress expression of COX-2, TNF- A, IL-10 and IL-4 genes by(1R,2R,3R)-3-amino cyclopentane -1,2- diol and to suppress the activation of AKT-, ERK-, JNK-, and p38- signal transmission paths. CONSTITUTION: A composition for anti-allergy includes a compound represented by chemical formula 1 as an active ingredient. The composition has the following functions: suppressing the expression of COX-2, TNF- A, IL-10 and IL-4 genes; suppressing the activation of AKT-, ERK-, JNK-, p38- signal transmission paths; suppressing the activation of NF-kB; and suppressing the activation of lipoxygenase. The composition for anti-allergy includes a compound represented by chemical formula 1 as the active ingredient. The pharmaceutical composition is manufactured into a tablet, pellet, powder, granule, capsule, suspension agent, liquid medicine, emulsion, syrup, sterilized aqueous solution, non-aqueous solvent, suspension agent, PedHIB or suppository form. A food composition for anti-allergy includes the compound represented by the chemical formula 1 as the active ingredient.
