“…On the other hand, the deprotonated form of Glu7 has a carboxylate ion (Fig. 6 ) which is considered more stable due to the presence of delocalized electrons 77 . Hence, the protonation of Glu7 does not happen to maintain the stability of Glu7.…”

Biophysical chemistry behind sickle cell anemia and the mechanism of voxelotor action

Sickle cell anemia disease has been a great challenge to the world in the present situation. It occurs only due to the polymerization of sickle hemoglobin (HbS) having Pro–Val–Glu typed mutation, while the polymerization does not occur in normal hemoglobin (HbA) having Pro–Glu–Glu peptides. It is also well confirmed that the oxygenated HbS (OHbS) does not participate in the polymerization, while the deoxygenated HbS (dHbS) does, which causes the shape of red blood cells sickled. After polymerization, the blood has a low oxygen affinity. Keeping this fact into consideration, only those drugs are being synthesized that stabilize the OHbS structure so that the polymerization of HbS can be stopped. The literature data showed no systematic description of the changes occurring during the OHbS conversion to dHbS before polymerization. Hence, an innovative reasonable study between HbA and HbS, when they convert into their deoxygenated forms, was done computationally. In this evaluation, physiochemical parameters in HbA/HbS before and after deoxygenation were studied and compared deeply. The computationally collected data was used to understand the abnormal behaviour of dHbS arising due to the replacement of Glu6 with Val6. Consequently, during the presented computational study, the changes occurring in HbS were found opposite/abnormal as compared to HbA after the deoxygenation of both. The mechanism of Voxelotor (GBT-440) action to stop the HbS polymerization was also explained with the help of computationally collected data. Besides, a comparative study between GBT-440 and another suggested drug was also done to know their antisickling strength. Additionally, the effect of pH, CO, CO2, and 2,3-diphosphoglycerate (2,3-DPG) on HbS structure was also studied computationally.

“…In addition, the introduction of CA reduced the parasitic reaction of Na þ with the electrolyte to produce by-products (RNaCO 3 , Na 2 CO 3 ), inhibiting the increase in CEI thickness. [125] 4. CEI at Low Temperature In practical industrial applications, SIBs must exhibit high energy and power densities, with low-temperature performance also critical.…”

“…[ 124 ] Lim et al used this property by introducing CA during their experiments to modulate the material‐generated CEI and electrochemical properties. [ 125 ] CA lost two H + per molecule in a neutral aqueous solution to achieve acid‐base equilibrium and stabilized in the chemical form of two –O–C=O ligands. The study found that CA molar ions (H 3 cit) were ionized to carboxylate ions (Hcit 2− ), and Hcit 2− was strongly bound to high‐spin iron (Fe HS ) ions on the PB surface, thus affecting the formation of CEI.…”

Sodium‐ion batteries (SIBs) have attracted attention due to their potential applications for future energy storage devices. Despite significant attempts to improve the core electrode materials, only some work has been conducted on the chemistry of the interface between the electrolytes and essential electrode materials. Therefore, the different cathode–electrolyte interfaces (CEIs) that form between various cathode materials and liquid electrolytes for SIBs are briefly reviewed, and the requirements of CEI performance in low‐temperature SIBs. Modifying the cathode materials and electrolyte formulas offers an efficient strategy for CEI enhancement. The summary and analysis, given in this article, may serve as a reference for the development of better sodium‐ion batteries.
