Andrade, Vitor Martins de; Bardaji, Eduard; Heras, Montserrat; Ramu, Vasanthakumar G.; Junqueira, Juliana Campos [UNESP]Made available in DSpace on 2020-12-10T19:58:54Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-05-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Kyotorphin (KTP, L-tyrosyl-L-arginine) is an endogenous analgesic neuropeptide first isolated from bovine brain in 1979. Previous studies have shown that kyotorphins posses...
The neuroprotective action of amidated-kyotorphin on amyloid β peptide-induced ...
Belo, Rita F.; Martins, Margarida L. F.; Shvachiy, Liana; Costa-Coelho, Tiago; de Almeida-Borlido, Carolina; Fonseca-Gomes, João; Neves, VeraKyotorphin (KTP, l-tyrosyl-l-arginine) is an endogenous dipeptide initially described to have analgesic properties. Recently, KTP was suggested to be an endogenous neuroprotective agent, namely for Alzheimer's disease (AD). In fact, KTP levels were shown to be decreased in the cerebrospinal fluid of patients with AD, and recent data showed that intracerebroventricular (i.c.v.) injection of KTP ameliorates memor...
Endothelium-mediated action of analogues of the endogenous neuropeptide kyotorp...
Perazzo, Juliana; Ferreira, Mónica Lopes; Santos, Sónia Sá; Serrano, Isa; Pinto, Antónia; Lima, Carla; Bardaji, Eduard; Tavares, IsauraKyotorphin (KTP) is an endogenous peptide with analgesic properties when administered into the central nervous system (CNS). Its amidated form (l-Tyr-l-Arg-NH2; KTP-NH2) has improved analgesic efficacy after systemic administration, suggesting blood-brain barrier (BBB) crossing. KTP-NH2 also has anti-inflammatory action impacting on microcirculation. In this work, selected derivatives of KTP-NH2 were synthesize...
Amidated and ibuprofen-conjugated kyotorphins promote neuronal rescue and memor...
Santos, Sónia Sá; Santos, Sara M.; Pinto, Antónia R. T.; Ramu, Vasanthakumar G.; Heras, Montserrat; Bardaji, Eduard; Tavares, IsauraChronic 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 antinociceptive dipeptide whose role as neuromodulator...
Side-effects of analgesic kyotorphin derivatives : advantages over clinical opi...
Ribeiro, Marta M. B.; Santos, Sónia Sá; Sousa, David S. C.; Oliveira, Margarida; Santos, Sara M.; Heras, Montserrat; Bardaji, Eduard; Tavares, IsauraThe adverse side-effects associated with opioid administration restrain their use as analgesic drugs and call for new solutions to treat pain. Two kyotorphin derivatives, kyotorphin-amide (KTP–NH2) and ibuprofen–KTP–NH2 (IbKTP–NH2) are promising alternatives to opioids: they trigger analgesia via an indirect opioid mechanism and are highly effective in several pain models following systemic delivery. In vivo si...
