ULTRASONIC STUDIES OF ANTIPROTOZOAL DRUG IN PROTIC AND APROTIC SOLVENTS AT 308.15 K

Latin American Applied Research - An international journal, 2014
 Ultrasonic velocities and density of various concentrations (0.01 to 0.10M) of anti protozoal drog “Diloxanide Furoate” in methanol, dimethyl formamide and 1,4-dioxan have been measured at 308.15 K by using single crystal variable path ultrasonic interferometer operating at 2 MHz and pycnometer respectively.

Divergent Synthesis of Polycyclic Derivatives via Gold Catalysis

European Journal of Organic Chemistry, EarlyView.
Gold(I)‐catalyzed cycloisomerization enables the formation of complex 3D structures from simple enyne precursors. This study presents a divergent strategy to synthesize functionalized bicyclic and tricyclic scaffolds from a common alkynyl ketone.

Localization of dexamethasone within dendritic core-multishell (CMS) nanoparticles and skin penetration properties studied by multi-frequency electron paramagnetic resonance (EPR) spectroscopy [PDF]

, 2016
The skin and especially the stratum corneum (SC) act as a barrier and protect epidermal cells and thus the whole body against xenobiotica of the external environment. Topical skin treatment requires an efficient drug delivery system (DDS).

Solvatochromism in Solvent Mixtures: A Practical Solution for a Complex Problem

Liquids
Many reactions are carried out in solvent mixtures, mainly because of practical reasons. For example, E2 eliminations are favored over SN2 substitutions in aqueous organic solvents because the bases are desolvated.

Effects of solvent and structure on the reactivity of 2-substituted nicotinic acids with diazodiphenylmethane in aprotic solvents [PDF]

, 2010
The rate constants for the reactions of diazodiphenylmethane (DDM) with 2-substituted nicotinic acids in nine aprotic solvents at 30°C were determined. The obtained second order rate constants in aprotic solvents, were correlated using the Kamlet-Taft

Memory of Chirality in Radical Addition–Translocation–Cyclization Cascades

Helvetica Chimica Acta, EarlyView.
Radical addition–translocation–cyclization cascades of chiral alkynes show striking memory of chirality (MoC), with strong retention of configuration when fast, polarity favored cyclization are involved. The most effective system employs a highly electron‐poor pentafluorobenzenesulfonyl group.

Role of High Fidelity Vs. Low Fidelity Experimental Data in Machine Learning Model Performance for Predicting Polymer Solubility

Macromolecular Rapid Communications, EarlyView.
The performance of machine learning models for classifying polymer solubility improves when a high‐fidelity experimental dataset is used compared to a low‐fidelity experimental dataset. This has important implications for justifying the value of spending additional time and resources preparing detailed experimental datasets.
