Charge transfer complexes of chloranil with drugs
The study of charge transfer (CT) complexes of chloranil with drugs (Naproxen, Nerolin, Methyl anthranilate, Isoxsuprine and Nylidrin) showed that there is a significant interaction between the acceptor and donors as evidenced by colour changes and absorption spectra. From the position of CT bands, the ionization potentials (IPs) of donors were evaluated using appropriate equations. The donor’s...
متن کاملTetramethyl-p-phenylenediamine oxidase reaction in Azotobacter vinelandii.
It was possible to quantitate the tetramethyl-p-phenylenediamine (TMPD) oxidase reaction in Azotobacter vinelandii strain O using turbidimetrically standarized resting cell suspensions. The Q(O2) value obtained for whole cell oxidation of ascorbate-TMPD appeared to reflect the full measure of the high respiratory oxidative capability usually exhibited by this genera of organisms. The Q(O2) valu...
متن کاملEnzymatic oxidation of tetramethyl-p-phenylenediamine and p-phenylenediamine by the electron transport particulate fraction of Azotobacter vinelandii.
The ability of the electron transport particulate fraction of Azotobacter vinelandii strain O to oxidize tetramethyl-p-phenylenediamine (TMPD) and p-phenylenediamine (PPD) was examined in detail. The highest specific activity for TMPD and PPD oxidation concentrated in the A. vinelandii O R(3) fraction. The A. vinelandii O R(3) fraction was used to develop a standard manometric assay which gave ...
متن کاملElectron transfer-based combination therapy of cisplatin with tetramethyl-p-phenylenediamine for ovarian, cervical, and lung cancers.
The platinum-based chemotherapy is the standard treatment for several types of cancer. However, cancer cells often become refractory with time and most patients with serious cancers die of drug resistance. Recently, we have discovered a unique dissociative electron-transfer mechanism of action of cisplatin, the first and most widely used platinum-based anticancer drug. Here, we show that the co...
متن کاملQuantitation of the tetramethyl-p-phenylenediamine oxidase reaction in Neisseria species.
The tetramethyl-p-phenylenediamine oxidase reaction commonly used in the Kovacs oxidase test was quantitatively estimated for various Neisseria species employing standardized resting cell suspensions. This genus of microorganisms exhibited very high tetramethyl-p-phenylenediamine oxidase rates comparable to that of Azotobacter and Pseudomonas, and this reaction was found to be a valid measureme...
