APPENDIX

1-DETAILED SYNOPSIS OF Ph.D.:
• Synthesis and Characterisation of Novel Sophorolipids and Their Biological Applications


Candida Bombicola yeast species is the preferred commercial strain for the synthesis of sophorolipids: glycolipid molecules with surface tension lowering capacities and biological activity. Sophorolipids biosurfactants attract quite some industrial attention due to the high yields of over 400 g/L which can be obtained by cultivations with C. bombicola.
In this study, full investigation and characterisation of the fermentation products (sophorolipids) provided by Croda Biotechnology were performed. The analysis included the use of 1D- and 2D-NMR, FT-IR, HPLC-MS, monomer, and linkage analysis employing HPAEC-PAD, and GC-MS to fully characterise the main fermentation products: sophorolipids lactone and acid forms. The characterisation also looked at materials presented in waste streams during the production. Interestingly, free sophorose (disaccharide) was identified in a number of the waste streams. The composition of the lactone waste stream was investigated utilizing HPAEC-PAD and NMR techniques. The results indicated the presence of glucose, sophorose and trace amount of isomaltose; these were separated using a liquid-liquid extraction technique followed by the isolation of each sugar using carbon: celite 535 column chromatography. Attempts were made to determine the origin of sophorose. In aqueous alkali sophorose was observed to undergo an epimerisation reaction and was converted to 2-O-β-D-glucopyranosyl-D-mannose. Another experiment was performed to investigate if enzyme(s) were present in the spent fermentation liquors, which were capable of hydrolysing sophorolipids to produce sophorose. The result suggested that sophorolipids were being converted into sophorose, glucose, isomaltose, and a glucolipid. Also in this study, a number of novel sophorolipids were synthesised starting from sophorose and using both enzyme and chemical glycosylation reactions. The lipase Novozyme 435 was used to catalyse the synthesis of the sophorolipid derivatives. Sophorose was used in the preparation of 2′′,3′,3′′,4′,4″,6′,6″-hepta-O-acetyl-α-D-sophoryl bromide, which was coupled to a range of different fatty alcohols. The interfacial properties and enzyme inhibition effect of a number of novel sophorolipids were explored successfully.
Finally, the anticancer activity of the newly synthesised sophorolipids was investigated in a separate programme of work using MCF7 and PC3 cell lines. The MTT assay results confirmed that sophorolipids derivatives possess antitumor activity as the IC50 results indicated that the purified compounds displayed potent growth inhibitory activity against these cell lines.

2-DETAILED SYNOPSIS OF MSc. PROJECTS:

• Nanocrystallisation to Enhance the Solubility and Dissolution Rate of Ibuprofen

In this research, ibuprofen microcrystals were reduced to the nanosized range using Solvent/Anti-solvent precipitation technique influenced by ultrasound energy in the presence of various stabilizers (surfactants) to inhibit the growth of nanocrystals during sono-crystallization process. The morphology of the formulated nanocrystals was characterized using various analytical techniques including: DSC, XRPD, Mesmerizer 2000, and FTIR. The purity and saturation solubility were determined using HPLC-UV and UV-Vis methods. Ibuprofen microcrystals/nanocrystals were formulated into tablet oral dosage form and the drug release profile was investigated and confirmed by dissolution study.

• Synthesis, Characterisation of New Cyclic and Non Cyclic Imines and their Analytical Application with some Metal-Ions

In this project, a series of novel crown imines (12-membered rings) and their half cyclized intermediate were synthesized via the reaction of different 1,2-diketones with various aliphatic and aromatic 1,2-diamines in the presence of acid catalyst. Structures and physicochemical properties of these cyclic imines were characterized by NMR, FT-IR, UV-VIS and AAS. Complex formation tendency was investigated using spot-test analysis which conducted with different transition-metal ions in solutions. Mole-ratio and continuous variation methods were used to determine the ligand to metal ratio. Crown imines-ligands and their complexes were supported into polyurethane foams and the chelating efficiency of these foams towards several transition metal ions was studies by batch system using UV/VIS & AAS techniques.
