Oral Dosed Organo‐Silica Nanoparticles Restore Glucose Homeostasis and β‐Cell Function in Diabetes Rats

Advanced Functional Materials, EarlyView.
An oral nanoplatform, MOP@T@D, which can maintain glucose homeostasis and restore islet β cells in diabetic rats is developed. It achieves efficient intestinal absorption and liver‐targeted delivery. The nanoparticle disintegrates only in response to hyperglycemia to release insulin on demand and provides antioxidant protection through selenoprotein ...

Antioxidant Ability of Chicoric Acid and Its Analogous Compounds.

NIPPON KAGAKU KAISHI, 1999
活性酸素を除去する機能を有する化合物の探索および合成は近年非常に注目を集めている。最近,薬草から抽出されたチコリ酸には抗酸化作用があることが報告された。本研究では,チコリ酸をはじめとする抗酸化剤の化学構造と抗酸化作用の関係を調べることを目的とした。まず,チコリ酸およびチコリ酸類縁構造をもつカエェオイルリンゴ酸の合成方法を検討した。抗酸化作用の評価は,遊離基除去作用についてはDPPH法を用い,化学量論的立場から評価した。抗酸化作用については,ラットの脳のホモジネートを用いて,抗酸化剤による脂肪酸化で生成するチオバルビツル酸反応物の生成抑制モル濃度によって検討した(ALP法)。抗酸化剤によるDPPHの消費速度と最終消費量から ...
