The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 4-Hydroxyquinoline-2-carboxylic Acid, is researched, Molecular C10H7NO3, CAS is 492-27-3, about Maternal protein restriction affects cardiovascular, but not respiratory response to L-glutamate microinjection into the NTS of conscious rats, the main research direction is glutamate microinjection protein cardiovascular respiratory maternal rat; L-glutamate microinjection; Maternal protein malnutrition; acid kinurenic microinjection; cardiac variability; glutamatergic system; hypertension; nucleus of the solitary tract; respiratory variability.Synthetic Route of C10H7NO3.
Dysregulation of glutamatergic neurotransmission (GN) is linked to sympathetic-respiratory overactivity and hypertension. We investigated whether maternal protein restriction is able to alter GN into the nucleus of the solitary tract (NTS) in adult offspring. Wistar rat dams were fed with control (NP; 17% protein) or low-protein (LP; 8% protein) diet during pregnancy and lactation, and their offspring were evaluated at 70-90d old. Direct measurements of mean arterial pressure (MAP), heart rate (HR), respiratory frequency (RF) and respiratory (RV) and cardiac (CV) variabilities were assessed in consciousness. The evaluation of GN into NTS over cardiovascular system were assessed by microinjections of unilateral glutamate (L-glu 0.5 nmol/100nL) and bilateral kynurenic acid (Kyn 2.5 nmol/50nL). The NP and LP groups were compared using unpaired Student′s t-test where p < 0.05 was considered significant. The LP exhibited higher MAP at rest (p = 0.03) and after L-glu microinjection (p = 0.04), as well as an increase over HR after Kyn microinjection when compared to the NP (p = 0.049). In the RV, the LP group showed an increase of the component-standard deviation 1 (p = 0.037) at rest. In the CV, the LP presented an increase of the low frequency (LF) component of the pulse interval (PI) (p = 0.034), a decrease of high frequency (HF) of the PI (p = 0.034), beyond an increased LF/HF ratio of the PI (p = 0.027) when compared to the NP. The kynurenic acid microinjection did not produce changes in RV or CV (p > 0.05). Altered GN into the NTS may contribute to augmented blood pressure in protein-restricted offspring.
As far as I know, this compound(492-27-3)Synthetic Route of C10H7NO3 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
