Photoexcitation dynamics of p-nitroaniline (pNA) and N,N-dimethyl-p-nitroaniline (DMpNA) in 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([C_nmim][NTf₂]) with different alkyl chain lengths (from C₂ to C₁₂) was investigated using transient absorption spectroscopy. The internal conversion rate from the excited state to the ground state was estimated from bleach recovery around the ground state absorption center, and the successive vibrational cooling rate in the ground state was estimated from the decay of the hot band observed at the red-edge of ground state absorption. The internal conversion rate slightly decreased with an increase in the alkyl-chain length of the cation, while the dependence of DMpNA was more significant than that of pNA. The extent of change was correlated with the change of the reaction free energy and solvent reorganization energy estimated from the absorption spectrum assuming that the internal conversion process is modeled by a back-electron-transfer process. The vibrational cooling rate estimated from the decay of hot-band absorption slightly decreased with an increase in the alkyl-chain length of the cation for both solutes. The hot-band decay of pNA was about 1.5-times faster than that of DMpNA, irresp. of the alkyl-chain length.

Recent studies have reported that using certain antihypertensive therapies such as angiotensin II receptor blockers (ARBs) is associated with mitigation of fatal outcomes and enhancing clin. features of patients having hypertension during coronavirus pandemic. Thus, in the current work an innovative, effective, white and sustainable spectrophotometric technique called paired wavelength data processing technique (PWDPT) was developed for evaluation of recommended antihypertensive combination therapies incorporating candesartan cilexetil (CAN) and hydrochlorothiazide (HCT). This technique included three methods, namely, absorbance resolution (AR), amplitude resolution (PR) and ratio extraction (RE). Linearity ranges were (5.0 μg/mL – 50.0 μg/mL) and (2.0 μg/mL – 24.0 μg/mL) for CAN and HCT, resp. Validation and confirmation of all suggested methods were conducted in accordance with ICH guidelines, producing satisfactory results within the accepted limits. Statistical comparison was achieved between the attained results from suggested methods and those attained from official methods, in which insignificant difference was existed. The suggested methods were successfully employed for identification of the studied drugs as well as determination of their spectral recognition and evaluation of the purity in their combined formulations. The proposed methods followed the principles of green anal. chem., where their greenness was evaluated and compared with the official potentiometric and HPLC methods via using four tools, namely, National Environmental Methods Index (NEMI), the Anal. Eco-Scale, the Green Anal. Procedure Index (GAPI) and Anal. greenness metric (AGREE) which affirmed the eco-friendly nature of the proposed methods. Moreover, studying the whiteness features was performed using the recently introduced RGB12 model.

The organic ligand 1-methyl-1H-benzo[d]imidazole-2-carbaldehyde (L’) was used to react with ZnX₂ (X = Cl and Br) under solvothermal conditions to obtain [Zn(L)₂(X)₂] (1, X = Cl; 2, X = Br). The ligand of L’ transforms into 1-methyl-1H-benzo[d]imidazole (L). The structures anal. shows that the L’ ligands of complex 1 and 2 coordinate in different way, which results different shapes in every structure. They are trans and cis isomers of Zn(II) mononuclear complexes induced by terminal anions. These also lead to the difference of weak interaction of complexes, thus affecting the mode of connection. Also, the electrospray ionization mass spectrometry (ESI-MS) data show that the main mol. fragment was [Zn(L)₂(X)]⁺ under the condition of 0 eV voltage. So those two complexes were relatively stable in CH₃CN. The single crystals of complex 1 showed blue green light, but complex 2 showed very obvious blue and white light under UV lamp, this difference may be due to the ion radius of coordination halogen.

Candesartan cilexetil is an angiotensin-receptor blocker that suffer from inadequit and variable oral bioavailability due to its poor aqueous solubility and presystemic metabolism Therefore, the objectives of this study was to enhance candesartan cilexetil dissolution with subsequent preparation of mouth dispersable tablets. The drug was precipitated from its ethanolic solution over Aerosil 200 as carrier for the deposited microcrystals. To improve surface wettability, the precipitation step was performed in presence of hydrophilic polymer. The selected polymers were polyvinylpyrrolidone 40T (PVP), hydroxypropylmethyl cellulose E5 (HPMC), Poloxamer 407 and polyethylene glycol6000 (PEG). The products were evaluated regarding dissolution pattern. Phys. characterization was also evaluated for selected formulations. Thermal behavior and X-ray powder diffraction results confirmed reduced drug crystalinity. Infra-red spectroscopy indicated drug-excipient compatibilty. All formulations showed imrovement in drug dissolution compared to pure drug. Presence of polymer resulted in higher initial release and dissolution efficiency. Best formulations regarding dissolution were successifly used in the preparation of oral dispersible tablets with fast drug release. Drug precipitation over carrier with large surface area in presence of hydrophilic polymer is a promising approach for enhancing dissolution rate of poorly soluble drugs.
