Control and Prediction of Solid-State of Pharmaceuticals : by Rajni Miglani Bhardwaj

By Rajni Miglani Bhardwaj

This thesis investigates various experimental and computational techniques for the invention of strong varieties. moreover, we achieve, as readers, a greater figuring out of the foremost elements underpinning solid-structure and variety. an immense a part of this thesis highlights experimental paintings performed on structurally very related compounds. one other very important part includes the effect of small adjustments in constitution and substituents on solid-structure and variety utilizing computational instruments together with crystal constitution prediction, PIXEL calculations, Xpac, Mercury and statistical modeling instruments. additionally, the writer provides a quick established procedure for solid-state shape screening utilizing Raman microscopy on multi-well plates to discover the experimental crystallization house. This thesis illustrates a cheap, functional and exact method to are expecting the crystallizability of natural compounds in line with molecular constitution by myself, and also highlights the molecular components that inhibit or advertise crystallization.

The examine of dietary supplementations has develop into more and more vital inside of orthodox institutions during the global, and because the marketplace for those items maintains to develop, so does the necessity for entire scientifically sound information regarding those items, their homes and strength wellbeing and fitness results.

Steroid-Protein Interactions

This can be the tale of steroid-protein interactions as one investigator sees it. Following the final proposal of this monograph sequence, it emphasizes the implications and interpretations acquired within the author's laboratory, and is accordingly a subjective account. spotting, how­ ever, that the dialogue of the topic will be incomplete if the fabric have been restricted to at least one scientist's paintings, the fundamental in attaining­ ments of different investigators were included.

Sometimes, the properties of two solid forms of a drug do not show substantial differences however they can, and often do, vary substantially with potentially significant impact on important physicochemical properties including solubility that may impact on the ease of manufacturing, stability of the drug in a formulated dosage form as well as bioavailability (Huang and Tong 2004; Llinàs and Goodman 2008).
