Journal ArticleDOI
Creation of nano eye-drops and effective drug delivery to the interior of the eye.
Yoshikazu Ikuta,Shigenobu Aoyagi,Yuji Tanaka,Kota Sato,Satoshi Inada,Yoshitaka Koseki,Tsunenobu Onodera,Hidetoshi Oikawa,Hitoshi Kasai +8 more
TL;DR: The utility of nano eye-drops utilising brinzolamide, a commercially available glaucoma treatment drug, as a target compound, is described, with results in high drug efficacy and applications as a next-generation ophthalmic treatment.
Journal ArticleDOI
Efficient Synthesis of Selenocarbonyl Compounds by Treating Carbonyl Compounds with Bis(1,5-cyclooctanediylboryl) Selenide
Kazuaki Shimada,Norikazu Jin,Michiko Kawaguchi,Kumiko Dobashi,Yumi Nagano,Manabu Fujimura,Eiichi Kudoh,Tomonari Kai,Norio Saito,Jun-ichi Masuda,Masaki Iwaya,Hiroyuki Fujisawa,Shigenobu Aoyagi,Yuji Takikawa +13 more
TL;DR: In this article, aldehydes and selenoketones were generated in situ by using bis(1,5-cyclooctanediylboryl) selenide; the resulting selenocarbonyl compounds were trapped with 2,3dimethyl-1,3-butadiene to give the corresponding [4+2] cycloadducts.
Journal ArticleDOI
Generation of 1,3-Chalcogenaza-1,3-butadienes by Thermal Cycloreversion of 2,4,6-Trisubstituted 6H-1,3,5-Oxachalcogenazines
Kazuaki Shimada,Kei Aikawa,Takuji Fujita,Masanobu Sato,Kurara Goto,Shigenobu Aoyagi,Yuji Takikawa,Chizuko Kabuto +7 more
TL;DR: In this article, thermal cycloreversion of 6H-1,3,5-oxathiazines or 1,3-selenaza-1.3-butadienes with substitutions at the C-2 and C-4 positions was used to obtain 1,4-adducts of the heterodienes in the presence of nucleophiles.
Journal ArticleDOI
Regioselective synthesis of polysubstituted pyridines via hetero-Diels-Alder reaction of isotellurazoles with acetylenic dienophiles
Kazuaki Shimada,Yukichi Takata,Yu Osaki,Akiko Moro-oka,Hisashi Kogawa,Maiko Sakuraba,Shigenobu Aoyagi,Yuji Takikawa,Satoshi Ogawa +8 more
TL;DR: In this paper, a pathway involving hetero-Diels-Alder reaction of isotellurazoles and the subsequent tellurium extrusion from the intermediary cycloadducts was proposed.
Journal ArticleDOI
Formation of Kinetically Stabilized Dithiiranes by Treating Thione S-Oxides Bearing a Bulky Substituent with Lawesson's Reagent.
TL;DR: In this paper, sterically crowded thione Soxides derived from d-camphor with Lawesson's reagent were treated with deoxygenation of the starting materials, and the mixtures were subjected to mCPBA oxidation to give the corresponding dithiirane S-oxides.
