Costa PPC, Campos R, Cabral PHB, Gomes VM, Santos CF, Waller SB, de Sousa EHS, Lopes LGDF, Fonteles MC, do Nascimento NRF. Antihypertensive potential of cis-[Ru(bpy) 2(ImN)(NO)] 3+, a ruthenium-based nitric oxide donor. Res Vet Sci 2020; 130:153-160. [PMID: 32193002 DOI: 10.1016/j.rvsc.2020.03.014] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2019] [Revised: 03/03/2020] [Accepted: 03/06/2020] [Indexed: 12/17/2022]
Abstract
The aim of this study was to investigate the antihypertensive properties of cis-[Ru(bpy)2ImN(NO)]3+ (FOR0811) in normotensive and in Nω-nitro-L-arginine methyl ester (L-NAME)-induced hypertensive rats. Vasorelaxant effects were analyzed by performing concentration response curve to FOR0811 in rat aortic rings in the absence or presence of 1H-[1,2,4]-oxadiazolo-[4,3,-a]quinoxalin-1-one (ODQ), L-cysteine or hydroxocobalamin. Normotensive and L-NAME-hypertensive rats were treated with FOR0811 and the effects in blood pressure and heart rate variability in the frequency domain (HRV) were followed. FOR0811 induced relaxation in rat aortic rings. Neither endothelium removal nor L-cysteine altered the FOR0811 effects. However, the incubation with ODQ and hydroxocobalamin completely blunted FOR0811 effects. FOR0811 administered intravenously by bolus infusion (0.01-1 mg/bolus) or chronically by using subcutaneous implanted osmotic pumps significantly reduced the mean arterial blood pressure. The effect was long lasting and did not induce reflex tachycardia. FOR0811 prevented both LF and VLF increases in L-NAME hypertensive rats and has antihypertensive properties. This new ruthenium complex compound might be a promising nitric oxide donor to treat cardiovascular diseases.

[PMID: 31732450 DOI: 10.1016/j.intimp.2019.105976] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Revised: 09/12/2019] [Accepted: 10/12/2019] [Indexed: 11/29/2022]
Abstract
BAY 41-2272 increases guanosine 3', 5'-cyclic monophosphate (cGMP) levels by stimulating soluble guanylate cyclase (sGC). In this study, we evaluated the effect of BAY 41-2272 on human T lymphocyte functions. Pretreating T cells for 24 h with BAY 41-2272 at 3 μM and 30 μM, followed by activation with 90 nM phorbol myristate acetate (PMA), inhibited interferon-gamma (IFN-γ) production, with 3 μM and 30 μM BAY causing 16.5-fold and 12.1-fold inhibition, respectively, compared to PMA alone (p < 0.05, one-way ANOVA followed by Tukey's test). We also observed suppressive effects on the expression of CD69, with 30 μM BAY causing 3.55-fold lower expression than PMA/ionomycin (p < 0.001 one-way ANOVA followed by Tukey's test), and T-bet, with 30 μM BAY causing 1.47-fold lower expression than PMA/ionomycin (p < 0.05, one-way ANOVA test followed by Tukey's test). Additionally, T lymphocyte proliferation was reduced 2.13-fold and 4.3-fold, respectively, by 3 μM BAY and 30 μM BAY compared to PMA/ionomycin (p < 0.01, p < 0.001, one-way ANOVA followed by Tukey's test). BAY 41-2272 inhibits human T lymphocyte function and may be explored as an immunomodulatory drug in patients with autoimmune/inflammatory diseases and lymphoproliferative syndromes.
