Much of chemistry, molecular biology, and drug design, are centered around the relationships between chemical structure and measured properties of compounds and polymers, such as viscosity, acidity, solubility, toxicity, enzyme binding, and membrane penetration.

For any set of compounds, these. The extent to which counterions bind to polyelectrolytes influences a variety of polymer-based applications, including polyelectrolyte enhanced ultrafiltration and forward osmosis using polyelectrolytes as draw agents. Potentiometric titrations of poly (2-vinylpyridine) (P2VP), poly (3-vinylpyridine) (P3VP), and poly (4-vinylpydine) (P4VP) were performed using HBr, HCl, HNO3.

A combined quantum mechanical (QM) and molecular mechanical (MM) potential has been developed for the study of reactions in condensed phases.

For the quantum mechanical calculations semiempirical methods of the MNDO and AM1 type are used, while the molecular mechanics part is treated with the CHARMM force field. Scheme 3. Biological active molecules 11 and 12 [9,10]. Synthesis of Ribose and NucleosideDerivatives year by year.

Introduction to tetrazole and click chemistry approaches was briefed in a concise way in order to help the readers have a basic understanding. Tetrazole and its derivatives play very important role in medicinal and pharmaceutical applications. The synthesis of tetrazole derivatives can be approached in ecofriendly approaches such as the use of water as solvent, moderate.

Although ionic liquids (ILs) have been known since the beginning of the last century () [], they are materials of recent advent in the field of green energy applications where their recognition as solvents or electrolytes has ever increased during the last definition ILs are molecular salts that melt at low temperatures, i.e.

around room temperature or below °C []. Over the past couple years, ChemMedChem has published quite a number of excellent papers covering novel antibiotics. We've compiled these recent articles in this Virtual Issue, which is free to read until December.

Voltammetry is the study of the current by applying the potential. This helps in the determination of the half-cell reactivity of the sample.

The voltammetry was first proposed by the Jaroslav Herovsky in by the principle of polarography. The analytical advantage of the voltammetry is the sensitivity with different concentrations of the samples. The last five years’ achievements in the synthesis and investigation of thermotropic ionic liquid crystals are reviewed.

The present review describes the mesomorphic properties displayed by organic, as well as metal-containing ionic mesogens. In addition, a short overview on the ionic polymer and self-assembled liquid crystals is given.

Most of these studies involve the optimization of culture conditions in shake flasks, due to its simplicity, whereas bioreactors provides high control over the relevant parameters, such as oxygen transfer and pH during all the cultivation process, and allows upscaling studies [, ].

A Review. using an Orrick–Erbar-type approach [45]. The method here proposed employs a group contribution technique to estimate the A and B parameters in the following equation: ln η ρM = A+ B T (1) where ηand ρare the viscosity in cP units and density in gcm−3 units, respectively.

M is the molecular weight and T is the abso-lute temperature. The origin of the isocyanide function was, of course, questioned, in the first paper in by Sica et al. 36 Garson et al. were the first to report that free cyanide was incorporated onto the terpene skeleton and was at the origin of the isocyanide group in the biosynthesis of diisocyanoadociane in a species of Amphimedon sponge (let us also.

Newly designed 2-azetidinone derivatives (4a-e) were synthesized in good yields and characterised by advanced spectroscopic studies.

The title compounds were evaluated for qualitative (zone of inhibition) by agar diffusion method against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa and Streptococcus pyogenes. The monooxygenase P BM-3 is a NADPH-dependent fatty acid hydroxylase enzyme isolated from soil bacterium Bacillus a pivotal member of cytochrome P superfamily, it has been intensely studied for the comprehension of structure–dynamics–function relationships in this class of enzymes.

Ventilator-associated pneumonia (VAP) is a pulmonary infection that appears after 2 days of endotracheal intubation and when invasive mechanical ventilation is used. VAP is considered the most common nosocomial infection in the intensive care unit (ICU) and presents high morbidity and mortality rates, principally when caused by multi-resistant bacteria.

This paper reports on the assessment of the quality and quantity of castor oil from castor seeds collected from different regions in Tanzania. The castor seeds from Arusha, Dar es Salaam, Dodoma, Iringa, Kagera and Morogoro regions in Tanzania were extracted by Soxhlet method using n-hexane and the oil yields were determined.

The yields were %, %, %. Moxifloxacin is a fluoroquinolone antibiotic with antibacterial activity. Moxifloxacin binds to and inhibits the bacterial enzymes DNA gyrase (topoisomerase II) and topoisomerase IV, resulting in inhibition of DNA replication and repair and cell death in sensitive bacterial species.
