BACKGROUND Fatty acids are indispensable constituents of mycolic acids that impart toughness & permeability barrier to the cell envelope of M. tuberculosis. Biotin is an essential co-factor for acetyl-CoA carboxylase (ACC) the enzyme involved in the synthesis of malonyl-CoA, a committed precursor, needed for fatty acid synthesis. Biotin carboxyl carrier(More)
Antimicrobial peptides (AMPs) are promising candidates as alternatives to conventional antibiotics for the treatment of resistant pathogens. In the last decades, new AMPs have been found from the cleavage of intact proteins with no antibacterial activity themselves. Bovine hemoglobin hydrolysis, for instance, results in AMPs and the minimal antimicrobial(More)
Chronic brain ischemia is a prominent risk factor for neurological dysfunction and progression for dementias, including Alzheimer's disease (AD). In rats, permanent bilateral common carotid artery occlusion (2VO) causes a progressive neurodegeneration in the hippocampus, learning deficits and memory loss as it occurs in AD. Kyotorphin (KTP) is an endogenous(More)
Recently, a designed class of efficient analgesic drugs derived from an endogenous neuropeptide, kyotorphin (KTP, Tyr-Arg) combining C-terminal amidation (KTP-NH2) and N-terminal conjugation to ibuprofen (Ib), IbKTP-NH2, was developed. The Ib moiety is an enhancer of KTP-NH2 analgesic action. In the present study, we have tested the hypothesis that KTP-NH2(More)
Amidated kyotorphin (L-Tyr-L-Arg-NH2; KTP-NH2) causes analgesia when systemically administered. The lipophilic ibuprofen-conjugated derivative of KTP-NH2 has improved analgesic efficacy. However, fast degradation by peptidases impacts negatively in the pharmacodynamics of these drugs. In this work, selected derivatives of KTP and KTP-NH2 were synthesized to(More)
