Thyrotropin-releasing hormone (TRH), a hypothalamic orally active neuropeptide, has been manifested in a wide range of biological responses. Besides its central role in regulating the pituitary-thyroid axis by simulating the release of thyrotropin, TRH has considerable influence on the activity of a number of neurobiological systems. Due to the therapeutic(More)
BACKGROUND Adverse cardiovascular effect of hypothyroidism has been identified in many studies. Early identification of patients with sub-clinical hypothyroidism may lead to early treatment and thereby favourable effect on cardiovascular morbidity and mortality. OBJECTIVES To find out the association of sub clinical hypothyroidism and left ventricular(More)
This study evaluated the effect of counterions on the physicochemical properties of prazosin salts. Salt forms of prazosin, namely, mesylate, besylate, tosylate, camsylate, oxalate, and maleate, were prepared and compared with the marketed anhydrous and polyhydrate forms of prazosin hydrochloride. Physicochemical characterization was performed in the order(More)
L-PGlu-(2-propyl)-L-His-L-ProNH₂ (NP-647) is a CNS active thyrotropin-releasing hormone (TRH) analog with potential application in various CNS disorders including seizures. In the present study, mechanism of action for protective effect of NP-647 was explored by studying role of NP-647 on epileptiform activity and sodium channels by using patch-clamp(More)

In the present study, the newly synthesized TRH analog (L-pGlu-(2-propyl)-L-His-l-ProNH(2); NP-647) was evaluated for its effects in in vitro (oxygen glucose deprivation (OGD)-, glutamate- and H(2)O(2)-induced injury in PC-12 cells) and in vivo (transient global ischemia) models of cerebral ischemic injury. PC-12 cells were subjected to oxygen and glucose(More)
In the present study, L-pGlu-(1-benzyl)-L-His-L-ProNH(2) (NP-355), a newer CNS active thyrotropin-releasing hormone (TRH) analog was evaluated for its antiepileptic potential. NP-355 (5, 10 and 20 micromol/kg; i.v.) pretreatment significantly delayed onset and reduced the frequency of convulsions in pentylenetetrazole-induced seizures. NP-355 was also found(More)
Thyrotropin-releasing hormone (TRH) and its analogs have a number of neurobiological functions and therapeutic uses in disorders of the central nervous system. In this study, the newly synthesized TRH analogs were evaluated for central nervous system activity in pentobarbital-induced sleeping in mice. The most potent TRH analog(More)
