Abstract:
The present invention relates to chlorin lactone, a method for manufacturing the chlorin lactone, and a use of the same. More specifically, provided in the present invention is a new photosensitive agent for reducing a side effect by increasing a tumor selectivity and enabling an effective treatment by a laser. Provided in the present invention for achieving the purpose is chlorin lactone of the following chemical formula 1. The chlorin lactone of the present invention can be selected as a candidate substance for a new photosensitive agent.
Abstract:
PURPOSE: An oligo(ethylene thiol) molecule substituted with deuterium and a manufacturing method thereof are provided to be used for mass analysis reference substance and to be applied in various fields. CONSTITUTION: A manufacturing method of an oligo(ethylene thiol) molecule substituted with deuterium comprises the following steps: a step of synthesizing 2-(2-(hex-5-enyloxy)ethoxy)ethanol or 2-(2-(undec-10-enyloxy)ethoxy)ethanol by reacting 6-bromohexene or 11-bromoundecene with NaOH solution and dithylene glycol mixed solution; a step of synthesizing 6-(2-(2-bromoethoxy)ethoxy)hex-1-ene or 11-(2-(2-bromo-ethoxy)ethoxy)undec-1-ene by reacting triphenyl phosphine and carbon tetrabromide with the product from the previous step; a step of synthesizing 2-(2-(2-(hex-5-enyloxy)ethoxy)ethoxy)ethanol-d4 or 2-(2-(2-(undec-10-enyloxy)ethoxy)ethoxy)ethanol-d4 by reacting NaH and ethylene glycol-D4 with the product from the previous step; a step of synthesizing S-6-(2-(2-(2-hydroxyethoxy)ethoxy)ethoxy)hexyl ethanethioate-d4 or S-11-(2-(2-(2-hydroxyethoxy)ethoxy)ethoxy)undecyl ethanethioate by reacting thioacetic acid and 2,2'-azobis(2-methylpropionamidine)dihydrochloride with the product from the previous step; and a step of synthesizing 2-(2-(2-(6-mercaptohexyloxy)ethoxy)ethoxy) ethanol-d4 or 2-(2-(2-(11-mercaptoundecyloxy)ethoxy)ethoxy)ethanol by reacting HCl with the product from the previous step.
