Multi-mechanistic chemical cleavage using certain metal complexes
(United States Patent and Trademark Office, 1998-08-25)
The invention is directed to a particular class of metal complexes, specifically certain texaphyrin metal complexes, which both hydrolyze and photocleave RNA, and which also both hydrolyze RNA and photocleave DNA. In one ...
Matrix-supported sapphyrins
(United States Patent and Trademark Office, 1998-09-15)
The invention relates to the field of polymer- and other matrix-supported sapphyrins. Disclosed are silica gel, glass, resin and other polymer- and matrix-supported sapphyrins and sapphyrin-containing chromatographic and ...
Fluoresence detection using texaphyrins
(United States Patent and Trademark Office, 1997-05-27)
Texaphyrins are provided for use as radiation sensitizers. Advantageous properties of texaphyrins for use as a radiation sensitizer include: i) a low redox potential which allows radiation-induced hydrated electrons to ...
Texaphyrin solid supports and devices
(United States Patent and Trademark Office, 1997-01-14)
The present invention provides various novel matrix-supported texaphyrins in which a polymeric or solid matrix is covalently modified by the addition of one or more texaphyrins or texaphyrin derivatives. Described are ...
Texaphyrin compounds having improved functionalization
(United States Patent and Trademark Office, 1997-02-04)
Texaphyrin metal complexes having improved functionalization include the addition of electron-donating groups to positions 2, 7, 12, 15, 18 and/or 21 and/or the addition of electron-withdrawing groups to positions 15 and/or ...
Photodynamic activity of sapphyrins
(United States Patent and Trademark Office, 1992-06-09)
The present invention includes a method to produce singlet oxygen from molecular oxygen generated by reaction with a sapphyrin compound excited at an absorbing wavelength to form a triplet species. Specifically, the sapphyrin ...
Membrane incorporation of texaphyrins
(United States Patent and Trademark Office, 2002-04-23)
Compositions having a texaphyrin-lipophilic molecule conjugate loaded into a biological vesicle and methods for imaging, diagnosis and treatment using the loaded vesicle are provided. For example, liposomes or red blood ...
