Name: N,2-Dihydroxybenzamide《Estrogen dampens central cannabinoid receptor 1-mediated neuroexcitation and pressor response in conscious female rats》 was published in 2022. The authors were Yao, Fanrong;Abdel-Rahman, Abdel A., and the article was included in《Biochemical Pharmacology (Amsterdam, Netherlands)》. The author mentioned the following in the article:
Activation of the rostral ventrolateral medulla (RVLM) cannabinoid receptor-1 (CB1R) causes neuronal nitric oxide synthase (nNOS)-dependent increases in sympathetic activity, blood pressure (BP) and heart rate (HR) in male rats. However, it remains unknown if the CB1R-mediated neurochem. and cardiovascular responses are influenced by the ovarian sex hormones, particularly estrogen (E2). Therefore, we studied the effects of intra-RVLM CB1R activation (WIN 55,212-2) on BP and HR in conscious female rats under the following hormonal states: (1) highest E2 level (proestrus sham-operated, SO); (2) E2-deprivation (ovariectomized, OVX); (3) OVX with E2 replacement (OVXE2). Intra-RVLM WIN55,212-2 elicited dose (100-400 pmol) dependent pressor and tachycardic responses, in OVX rats, which replicated the reported responses in male rats. However, in SO and OVXE2 rats, the CB1R-mediated pressor response was attenuated and the tachycardic response reverted to bradycardic response. The neurochem. findings suggested a key role for the upregulated RVLM sympathoexcitatory mols. phosphorated protein kinase B, phosphorated nNOS and reactive oxygen species in the exaggerated CB1R-mediated BP and HR responses in OVX rats, and an E2-dependent dampening of these responses. The intra-RVLM WIN55212-2-evoked cardiovascular and neurochem. responses were CB1R-mediated because they were attenuated by prior CB1R blockade (AM251). Our findings suggest that attenuation of RVLM neuroexcitation and oxidative stress underlies the protection conferred by E2, in female rats, against the CB1R-mediated adverse cardiovascular effects. To complete the study, the researchers used N,2-Dihydroxybenzamide (cas: 89-73-6) .
N,2-Dihydroxybenzamide(cas: 89-73-6) is widely used for a variety of roles in biology and medicine as a chelating therapy.Name: N,2-DihydroxybenzamideIt inhibits bacterial or fungi growth by interfering with iron uptake. It is also active as a inhibitor of enzyme involved in tumour growths.
