Solid Lipid Nanoparticles (SLNs) are a promising new drug delivery system that can overcome issues with solubility and stability of lipophilic drugs. SLNs are solid colloidal particles ranging in size from 100-1000nm that are composed of physiological lipids. They can incorporate both hydrophilic and hydrophobic drugs in either a homogeneous matrix or an enriched shell or core depending on production methods. SLNs have advantages over other nanoparticles in being biocompatible, physically stable, and able to provide controlled drug release over prolonged periods. However, challenges remain in fully controlling particle size, lipid crystallinity, and drug release kinetics.
Chemistry of Natural Products, Morphine Alkaloids.pptxJubair Sikdar
Jubair Sikdar presented on morphine alkaloids. Morphine is extracted from unripe poppy capsules. Structural changes to morphine's hydroxyl groups and other parts of the molecule impact its analgesic potency. Replacing the phenolic hydroxyl reduces analgesic effects, while replacing the alcoholic hydroxyl with a methoxy or ethoxy group increases potency. Morphine is used to reduce both acute and chronic pain, decrease shortness of breath symptoms, treat convulsions, enhance the efficacy of anesthetics, and counteract the effects of toxic alkaloids.
Derivative spectroscopy involves converting a normal absorption spectrum into its first or second derivative spectrum. This allows for more precise determination of the wavelength of maximum absorption and improved spectral resolution. The first derivative spectrum plots the rate of change of absorbance versus wavelength and shows a maximum, minimum and zero crossing at the absorption band's wavelength. The second derivative shows two satellite maxima with an inverted band minimum at the wavelength of maximum absorption. Area under curve spectroscopy calculates the integrated absorbance value over a specified wavelength range, graphically representing the area under the absorption curve. Both techniques have applications in pharmaceutical analysis for multicomponent assays and determination of physical constants.

This document provides an overview of nuclear magnetic resonance (NMR) spectroscopy. It discusses the basic principles and instrumentation of NMR, solvent requirements, relaxation processes, chemical shifts and factors that affect chemical shifts. Common NMR solvents like CDCl3 and DMSO are described. Relaxation is explained as either spin-lattice (longitudinal) or spin-spin (transverse) processes. Chemical shifts result from shielding or deshielding of nuclei by electrons. Tetramethylsilane is used as an internal reference standard. Electronegativity, inductive effects, anisotropic effects, van der Waals deshielding and hydrogen bonding can influence chemical shifts.
In Vitro Antioxidant Studies of Whole Plant Ethanolic Extract of Blepharisrep...pharmaindexing
The document describes an in vitro study of the antioxidant properties of the whole plant ethanolic extract of Blepharisrepens (Vahl) Roth. Both the ethanol and aqueous extracts showed high scavenging activity against DPPH radicals at 500 μg/ml concentration. The ethanol extract was more effective at scavenging DPPH and nitric oxide radicals, while the aqueous extract more effectively scavenged hydroxyl and superoxide radicals. Both extracts showed moderate lipid peroxidation inhibition and contained flavonoids and phenols that contribute to their antioxidant effects. The study suggests Blepharisrepens has substantial antioxidant activity through its flavonoid content.

The purpose of this presentation is to:
• Indicate the stereochemical terms that are obsolete
• Point out and discuss the use, misuse, disuse and abuse of
stereochemical lexicon
• Inform the new directions in nomenclature system of chiral

Valliappan Kannappan presented on the importance of chirality. Chirality is a key characteristic of biological molecules and life processes. Most biological macromolecules like proteins, DNA, RNA, sugars and amino acids are chiral. Many drugs are also chiral, and the biological targets they interact with are also chiral. For this reason, the specific chiral form of a drug is important. Regulatory agencies now require separation and characterization of chiral drug molecules. Many commonly used therapeutic agents are employed as single enantiomers rather than racemic mixtures for increased efficacy and safety. Chirality will continue to be an important consideration in life science research and drug development.
This document provides guidance on appropriate terminology for describing stereochemistry and stereoisomers in drugs. It discusses preferred and obsolete terms, corrections for misnomers and syntax errors, and guidelines for prefixes in stereochemically informative generic names. Specifically, it advises using "stereogenic centers" instead of "chiral centers/multichiral", reserving "homochiral" to compare like configurations rather than describing a substance, and labeling an enantiopure sample simply as "enantiopure". The document aims to promote clear and accurate communication about stereochemistry in drugs.
Understand the behavior of mirror-image molecules. Behavior depends on the environment (chiral/achiral) to which the molecule is exposed. When both the players (the target and the drug molecule) are chiral, there is a need for chiral perspective.
