Abstract
Sickle cell disease (SCD) treatment and management remain a challenging puzzle especially among developing Nations. Chrysin's sickling-suppressive properties in human sickle (SS) erythrocytes in addition to its effect on AA-genotype erythrocytes were evaluated. Sickling was induced (76%) with 2% sodium metabisulphite at 3 h. Chrysin prevented (81.19%) the sickling and reversed same (84.63%) with strong IC50s (0.0257 µM and 0.00275 µM, respectively). The levels of oxygenated haemoglobin in the two groups (before and after induction approaches) were similar but significantly (P < 0.05) higher than that of SS erythrocytes (the 'induced' control), with chrysin-treated AA-genotype showing no effects relative to the untreated. The level of deoxygenated haemoglobin in the 'induced' control group was significantly (P < 0.05) higher than those of the chrysin-treated SS erythrocytes. Normal and chrysin-untreated erythrocytes (AA-untreated) were significantly more resistant to osmotic fragility than the SS-untreated. However, treatment with chrysin significantly reduced the osmotic fragility of the cells relative to the untreated cells. Furthermore, chrysin treatment significantly lowers the high level of 2,3-diphosphoglycerate (2,3-DPG) observed in the sickle erythrocytes, with no effects on AA-genotype erythrocytes. Based on functional chemistry, chrysin treatment alters the functional groups in favour of its antisickling effects judging from the observed bends and shifts. From metabolomics analysis, it was observed that chrysin treatment favors fatty acid alkyl monoesters (FAMEs) production with concomitant shutting down-effects on selenocompound metabolism. Thus, sickling-suppressive effects of chrysin could potentially be associated with modulation of oxygenated and deoxygenated haemoglobin via alteration of human sickle erythrocyte's functional chemistry and metabolic pathways implicated in SCD crisis.

Abstract
Anemia, characterized by a decrease of the hemoglobin level in the blood and a reduction in carrying capacity of oxygen, is a major public health problem which affects people of all ages. The methods used to treat anemia are blood transfusion and oral administration of iron-based supplements, but these treatments are associated with a number of side effects, such as nausea, vomiting, constipation, and stomach pain, which limit its long-term use. In addition, oral iron supplements are poorly absorbed in the intestinal tract, due to overexpression of hepcidin, a peptide hormone that plays a central role in iron homeostasis. In this review, we conducted an analysis of the literature on biologically active compounds and plant extracts used in the treatment of various types of anemia. The purpose of this review is to provide up-to-date information on the use of these compounds and plant extracts, in order to explore their therapeutic potential. The advantage of using them is that they are available from natural resources and can be used as main, alternative, or adjuvant therapies in many diseases, such as various types of anemia.

J Chromatogr B Analyt Technol Biomed Life Sci 2020; 1154:122283. [PMID: 32862024 DOI: 10.1016/j.jchromb.2020.122283] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 07/10/2020] [Accepted: 07/24/2020] [Indexed: 02/02/2023]
Abstract
Hydroxyurea (HU) is the first-ever approved drug by the United States Food and Drug Administration (USFDA) for the management of sickle cell anemia (SCA). However, its treatment is associated with severe liabilities like myelosuppression. Therefore, the aim of the present investigation was to identify phytotherapeutics through assessment of the pharmacokinetic interaction of HU with dietary bioflavonoids followed by elucidation of the same phytoconstituents for their ability to protect HU-induced toxicity in hematological profile. In this direction, we developed a sensitive ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method to estimate HU in rat plasma at first and then validated as per USFDA guidelines as there is no such precedent in the literature. A simple plasma protein precipitation method was employed for plasma sample processing. The separation was achieved in gradient mode using Syncronis HILIC column (100 × 4.6 mm, 3 μm) with a mobile phase composition of water containing 0.1% (v/v) formic acid and acetonitrile. Ionization was carried out in positive heated-electrospray ionization (H-ESI) mode. Detection was done in selected reaction monitoring (SRM) mode with m/z 77.1 > 44.4 and m/z 75.1 > 58.2 for HU and methylurea (internal standard), respectively. All the validation parameters were within the acceptable criteria. This bioanalytical method was found to be useful in assessing the preclinical pharmacokinetic interaction of HU. Concomitant administration of chrysin or quercetin with HU in rats significantly enhanced the oral exposure of HU. Lowering of total red blood cells (RBC) and hemoglobin (Hb) level by HU in rats was significantly improved in the presence of chrysin, quercetin, and naringenin. Overall, both chrysin and quercetin showed potential to be a promising phytotherapeutics for concomitant therapy with HU to combat its dose-dependent side effects.

Abstract
In red blood cells, hemoglobin iron represents the most plausible candidate to catalyze artemisinin activation but the limited reactivity of iron bound to hemoglobin does not play in favor for its direct involvement. Denatured hemoglobin appears a more likely candidate for artemisinin redox activation because it is expected to contain reactive iron and it has been described to release free heme and/or iron in erythrocyte. The aim of our study is to investigate, using three different methods: fluorescence, electron paramagnetic resonance and liquid chromatography coupled to mass spectrometry, how increasing the level of accessible iron into the red blood cells can enhance the reactive oxygen species (ROS) production derived from artemisinin. The over-increase of iron was achieved using phenylhydrazine, a strong oxidant that causes oxidative stress within erythrocytes, resulting in oxidation of oxyhemoglobin and leading to the formation of methemoglobin, which is subsequently converted into irreversible hemichromes (iron (III) compounds). Our findings confirmed, using the iron III chelator, desferrioxamine, the indirect participation of iron (III) compounds in the activation process of artemisinins. Furthermore, in strong reducing conditions, the activation of artemisinin and the consequent production of ROS was enhanced. In conclusion, we demonstrate, through the measurement of intra-erythrocytic superoxide and hydrogen peroxide production using various methods, that artemisinin activation can be drastically enhanced by pre-oxidation of erythrocytes.
