Peptides derived from human and bovine lactoferricin were designed, synthesized, purified, and characterized using RP-HPLC and MALDI-TOF-MS. Specific changes in the sequences were designed as (i) the incorporation of unnatural amino acids in the sequence, the (ii) reduction or (iii) elongation of the peptide chain length, and (iv) synthesis of molecules with different number of branches contain...

UNLABELLED The leaves of Ritchiea capparoides var. longipedicellata (Capparidaceae) is used in ethnomedicine in South-Western Nigeria to treat infectious and parasitic diseases. This study was aimed at identifying the compound(s) that are responsible for the antimicrobial and antiplasmodial activities of the leaves and also to contribute to the chemistry of the plant species. A 70 % aqueous eth...

The in vitro activity of sparfloxacin (AT-4140; RP 64206), a new fluoroquinolone, was compared with those of 10 other agents against 1,222 clinical isolates. Sparfloxacin and ciprofloxacin were the most active quinolones against members of the family Enterobacteriaceae and nonfermenting gram-negative bacilli; sparfloxacin had superior activity against gram-positive cocci in comparison with the ...

BACKGROUND Frequent opportunist fungal infections and the resistance to available antifungal drugs promoted the development of new alternatives for treatment, like antifungal drug combinations. AIMS This work aimed to detect the antifungal synergism between statins and azoles by means of an agar-well diffusion bioassay with Saccharomyces cerevisiae ATCC 32051 and Candida utilis Pr(1-2) as tes...

Linear, dimeric, tetrameric, and cyclic peptides derived from lactoferricin B-containing non-natural amino acids and the RWQWR motif were synthesized, purified, and characterized using RP-HPLC, MALDI-TOF mass spectrometry, and circular dichroism. The antibacterial activity of peptides against Escherichia coli ATCC 11775, Stenotrophomonas maltophilia ATCC 13636, and Salmonella enteritidis ATCC 1...

introduction sectoral retinitis pigmentosa (rp) is a rare clinical condition. case presentation we present a 60-year-old female with a history of mild night blindness and decreased vision in the left eye for about 15 years. conclusions fundus examination revealed retinal pigmentary changes in the inferotemporal sector and reduced arterial caliber. in addition, fundus autofluorescence, fluoresce...

eperisone hydrochloride is a skeletal muscle relaxant and paracetamol is cyclooxygenase inhibitor. these drugs in combination are used as antispasmodics. a simple, specific, precise and accurate method was developed, namely reverse phase high performance liquid chromatography for simultaneous estimation of eperisone hydrochloride and paracetamol in tablet dosage form. in rp-hplc method separati...
