Abstract
Cisplatin (CIS) is an effective chemotherapeutic agent against different cancers. The use of CIS is associated with acute lung injury (ALI) and other adverse effects, and oxidative stress and inflammation were implicated in its toxic effects. Candesartan (CAN), an angiotensin II (Ang II) receptor blocker, showed beneficial effects against oxidative stress and inflammation. Therefore, this study investigated the potential of CAN to prevent CIS-induced oxidative stress, inflammation, and lung injury in rats, pointing to the involvement of TLR4/NF-κB, JAK1/STAT3, PPARγ, and Nrf2/HO-1 signaling. The rats received CAN (5 mg/kg) for 10 days and were challenged with a single dose of CIS (7 mg/kg) on day 7. CIS caused injury to the alveoli and the bronchial tree, increased lipid peroxidation, nitric oxide, myeloperoxidase, TLR-4, NF-κB p65, iNOS, TNF-α, IL-6, IL-1β, and caspase-3, and decreased cellular antioxidants and IL-6 in the lungs of rats. CAN effectively prevented tissue injury, suppressed TLR-4/ NF-κB signaling, and ameliorated oxidative stress, inflammatory markers, and caspase-3 in CIS-administered rats. CAN enhanced antioxidants and IL-10, decreased Ang II, increased Ang (1–7), suppressed the phosphorylation of JAK1 and STAT3, and upregulated SOCS3 in CIS-administered rats. These effects were associated with the downregulation of Keap1 and enhanced Nrf2, GCLC, HO-1, and PPARγ. In conclusion, CAN prevented CIS-induced lung injury by attenuating oxidative stress, suppressing TLR-4/NF-κB and JAK1/STAT3 signaling, Ang II, and pro-inflammatory mediators, and upregulating PPARγ, and Nrf2/HO-1 signaling.

Abstract
Preeclampsia (PE) is one of the leading causes of maternal morbidity and mortality in pregnant women. This study aimed to investigate the potential impact and regulatory mechanisms of bone morphogenetic protein receptor 2 (BMPR2) on the progression of PE. We obtained placental tissues from pregnant women with PE and normal pregnant women, and the results showed that BMPR2 was expressed at low levels in the tissue from PE women. Genetic knockdown of BMPR2 increased the proliferation and invasion of cultured trophoblast cells, whereas its overexpression reduced these characteristics. Bioinformatics analysis and luciferase reporter gene assays confirmed that BMPR2 is a direct target of miR-21. Overexpression of a miR-21 inhibitor promoted the growth and invasiveness of trophoblast cells, whereas the opposite results were observed for the miR-21 mimic. Furthermore, miR-21 was sponged by the lncRNA MEG3, and shRNA inhibition of MEG3 reduced trophoblast cell growth and invasiveness. miR-21 was upregulated in the tissues from PE women, whereas MEG3 was downregulated, and the two were negatively correlated. Collectively, this study demonstrates that the lncRNA MEG3 acts as a sponge for miR-21, which regulates BMPR2 expression and promotes trophoblast cell proliferation and invasiveness, thereby preventing the development of PE. These findings provide novel insight into a targeted therapy that could be used to treat or prevent the development of PE.

Abstract
During the last decades, much attention has been focused on SNEDDS approach to resolve concerns of BCS II class drugs with accentuation on upgrading the solubility and bioavailability. The present hypothesis confirms the theory that SNEDDS can reduce the impact of food on Candesartan solubilization, thereby offering the potential for improved oral delivery without co-administration with meals. The present studies describe quality-by-design-based development and characterization of Candesartan loaded SNEDDS for improving its pharmacodynamic potential. D-optimal mixture design was used for systematic optimization of SNEDDS, which showed globule size of 13.91 nm, more rapid drug release rate of >90% in 30 min and 16 s for self-emulsification. The optimized formulations were extensively evaluated, where an in vitro drug release study indicated up to 1.99- and 1.10-fold enhancement in dissolution rate from SNEDDS over pure drug and marketed tablet. In vivo pharmacodynamic investigation also showed superior antihypertensive potential of SNEDDS in normalizing serum lipid levels as compared to pure drug and marketed tablet that was executed on male Wistar rats. Overall, this paper reports successful systematic development of candesartan-loaded SNEDDS with distinctly improved biopharmaceutical performance. This research work interpreted a major role of SNEDDS for enhancing the rate of dissolution and bioavailability of poorly water soluble drugs.

Abstract
Microglia are diverse cells that acquire different functional phenotypes in
response to microenvironment in which they reside. Several transcriptional
regulators have been identified that regulate different microglia phenotypes.
They are mainly stimulated into two opposing phenotypes, classically (M1) and
alternatively (M2) phenotype. Regulating microglia polarization from M1 to M2
state has been suggested as a potential therapeutic approach in treatment of CNS
disorders. Candesartan, an angiotensin II type I receptors antagonist, exerts
beneficial effects for antioxidant, anti-inflammation, neurotrophic, and
anti-apoptotic function. However, the effect of candesartan on microglia
polarization and underlying mechanisms remain unknown. In this study, the
resting microglia were stimulated to M1 microglia with lipopolysaccharide (LPS)
and interferon-γ (IFN-γ), and then treated with vehicle or candesartan for 24 h.
RT-PCR was utilized to detect the mRNA expression of microglia phenotype markers
and inflammatory cytokines. Microglia phenotype markers and toll-like receptor 4
(TLR4)/nuclear factor kappa B (NF-κB) pathway were determined by western blot. A
neuron-microglia co-culture system was used to determine whether candesartan
could ameliorate the neurotoxic effect of M1 microglia to oxygen-glucose
deprivation (OGD) neuron. Candesartan treatment reduced the expression of M1
markers, and increased M2 markers. Meanwhile, candesartan reduced fluorescence
intensity and protein level of M1 marker and enhanced M2 marker. Candesartan
also regulated the neuroinflammatory response via reducing the release of
pro-inflammatory cytokines and increasing anti-inflammatory cytokines in LPS +
IFN-γ stimulated BV2 cells. Candesartan markedly inhibited the protein level of
TLR4, the phosphorylation of IKBα and p65, and suppressed nuclear translocation
of NF-κB p65. BAY 11-7085, a NF-κB inhibitor, remarkably enlarged the inhibitory
effect of candesartan on NF-κB pathway. In addition, M1 phenotype microglia
exacerbated post-OGD N2a cells death and LDH release, whereas candesartan
reversed such neurotoxic effect. Candesartan treatment may ameliorate
stroke-induced neuronal damage through shifting microglia to M2 phenotype in a
TLR4/NF-κB-dependent manner.

The bioflavonoid troxerutin prevents gestational hypertension in mice by inhibiting STAT3 signaling. Hypertens Res 2020; 44:399-406. [PMID: 33122822 DOI: 10.1038/s41440-020-00568-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Revised: 08/13/2020] [Accepted: 09/23/2020] [Indexed: 11/08/2022]
Abstract
Gestational hypertension is a high-risk disease for women, and the current treatments have limited efficacies. Here, we aimed to evaluate troxerutin, which is a natural monomer of flavone, in the treatment of gestational hypertension. Pregnant mice with or without pregnancy-induced hypertension (PIH) were treated with troxerutin (20 and 40 mg/kg) or vehicle. Blood pressure and proteinuria were monitored during treatment. The expression of vasodilation converting enzyme (VCE), angiotensin, TNFα, IL-6, IL-1β and IL-10 was measured by enzyme-linked immunosorbent assay (ELISA). Oxidative stress was assessed by measuring the reactive oxygen species (ROS) levels and antioxidant enzyme concentrations. Western blot analysis was used to assess the expression of p-STAT3, STAT3, SHP-1, and RNF6. Troxerutin reduced blood pressure and the expression of VCE, angiotensin, urinary protein and pro-inflammatory cytokines in a dose-dependent manner while increasing the expression of anti-inflammatory cytokines. The levels of ROS were decreased, and the levels of antioxidant enzymes were increased. Troxerutin treatment significantly suppressed STAT3/RNF6 signaling. Overexpression of RNF6 attenuated the effects of troxerutin in ameliorating inflammation and oxidative stress. Our data support the use of troxerutin for reducing gestational hypertension due to the role of troxerutin in reducing inflammation and oxidative stress.

Abstract
The aim of this work was to assess the impact of an excipient in a pharmaceutical formulation containing candesartan cilexetil over the decomposition of the active pharmaceutical ingredient and to comparatively investigate the kinetics of degradation during thermolysis in an oxidative atmosphere under controlled thermal stress. To achieve this, the samples were chosen as follows: pure candesartan cilexetil and a commercial tablet of 32 mg strength. As a first investigational tool, Universal attenuated total reflection Fourier transform infrared (UATR-FTIR) spectroscopy was chosen in order to confirm the purity and identity of the samples, as well as to check if any interactions took place in the tablet between candesartan cilexetil and excipients under ambient conditions. Later on, samples were investigated by thermal analysis, and the elucidation of the decomposition mechanism was achieved solely after performing an in-depth kinetic study, namely the use of the modified non-parametric kinetics (NPK) method, since other kinetic methods (American Society for Testing and Materials—ASTM E698, Friedman and Flynn–Wall–Ozawa) led to inadvertencies. The NPK method suggested that candesartan cilexetil and the tablet were degraded by the contribution of two steps, the main being represented by chemical degradation and the secondary being a physical transformation. The excipients chosen in the formulation seemed to have a stabilizing effect on the decomposition of the candesartan cilexetil that was incorporated into the tablet, relative to pure active pharmaceutical ingredient (API), since the apparent activation energy for the decomposition of the tablet was 192.5 kJ/mol, in comparison to 154.5 kJ/mol for the pure API.
