Two polyacetylenic antibiotics, peniophorin A and B, have been isolated from a strain of Peniophora affinis. Both have antibacterial and antifungal activity, but B is 3 to 20 times more active than A. Gram-positive cocci and a strain of Proteus vulgaris were especially susceptible to these two antibiotics. Both peniophorins contained an aromatic ring; B was an acid, and A was neutral. Peniophor...
Luminescence spectra are reported for trans-[MoOCl(CN-t-Bu)(4)]BPh(4) and trans-[MoOF(pyridine)(4)]BPh(4). The maxima of the broad luminescence bands are at energies of 12000 and 13000 cm(-1), respectively. Resolved vibronic structure involves the metal-oxo stretching mode with a vibrational frequency of approximately 950 cm(-1) (Raman) in both compounds. The pressure behavior of the luminescen...
Nucleic acid oxidation plays an important role in the pathophysiology progress of a variety of diseases. 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxo-dGsn) and 8-oxo-7,8-dihydroguanosine (8-oxo-Gsn), which originate from DNA and RNA oxidation, were the most widely used indicators for oxidative stress. The study investigated the relation between 8-oxo-dGsn, 8-oxo-Gsn, and CKD. 146 patients with CK...
