Abstract
In the previous studies, gemini lipoamino acids (GLAA) were always synthesized by complex multistep organic synthesis, which involved a large number of byproducts and organic solvents. To develop a straightforward, efficient, and renewable synthesis strategy for GLAA, in this study, a type of novel green solvents, natural deep eutectic solvents (NADESs), were adopted as the solvents for these reactions. Five commercial enzymes were involved in the enzyme screening section, and Candida antarctica lipase B (CALB) tended to have the best performance in NADESs systems. The optimization procedure was performed using the Taguchi crossed array method and the highest yield of GLAA (59.14 ± 0.51%) was obtained in choline chloride-glycerol (C-Gly). The purification procedure was carried out with ethyl acetate and water, and the isolate yield ranged from 86.31 ± 2.36 to 91.34 ± 2.26%. With 10 times recycling, the yield of GLAA in C-Gly decreased from 59.14 ± 0.51 to 51.31 ± 0.68%. Interestingly, a synergistic effect of CALB and NADESs was found in the enzymatic synthesis of GLAA, which can be attributed to fatty acids being activated by chloride ions via hydrogen-bonding interactions and resulting in an enhancement in its electron-attracting ability.

Abstract
Biosurfactant compounds have been studied in many applications, including biomedical, food, cosmetic, agriculture, and bioremediation areas, mainly due to their low toxicity, high biodegradability, and multifunctionality. Among biosurfactants, the lipoplexes of lipoaminoacids play a key role in medical and pharmaceutical fields. Lipoaminoacids (LAAs) are amino acid-based surfactants that are obtained from the condensation reaction of natural origin amino acids with fatty acids or fatty acid derivatives. LAA can be produced by biocatalysis as an alternative to chemical synthesis and thus become very attractive from both the biomedical and the environmental perspectives. Gemini LAAs, which are made of two hydrophobic chains and two amino acid head groups per molecule and linked by a spacer at the level of the amino acid residues, are promising candidates as both drug and gene delivery and protein disassembly agents. Gemini LAA usually show lower critical micelle concentration, interact more efficiently with proteins, and are better solubilising agents for hydrophobic drugs when compared to their monomeric counterparts due to their dimeric structure. A clinically relevant human gene therapy vector must overcome or avoid detect and silence foreign or misplaced DNA whilst delivering sustained levels of therapeutic gene product. Many non-viral DNA vectors trigger these defence mechanisms, being subsequently destroyed or rendered silent. The development of safe and persistently expressing DNA vectors is a crucial prerequisite for a successful clinical application, and it one of the main strategic tasks of non-viral gene therapy research.

Abstract
First bioorganic synthesis of a novel phenolic lipid isolated from natural source. The phenolic lipid was synthesized following a chemo-enzymatic approach. Lipase-catalyzed transformation was employed in the synthesis. The prepared phenolic lipid exhibited excellent antioxidant potential. The prepared phenolic lipid could have great potential in food and cosmetic formulations.
The first synthesis of a phenolic natural monoacylglycerol (1- [11-(ferulyloxy) undecanoyl)] glycerol) was carried out by bioorganic synthesis starting from ferulic acid. The synthetic route of the target lipidic compound was designed involving a chemo-enzymatic approach using immobilized Candida antarctica lipase as biocatalyst in two of the steps conducted in organic medium. The prepared lipidic compound was characterized by using spectral data and evaluated for antimicrobial, antioxidant and cytotoxic studies to examine its potential. The synthesized compound showed moderate antimicrobial activity and showed very good antioxidant activity in DPPH radical scavenging assay and also in oxidation inhibition in soybean oil by differential scanning calorimetry. The cytotoxic studies of the synthetic lipid showed promising activity against A549 and HeLa cancer cell lines with IC50 values of 9.102 and 9.886 μM respectively. The prepared compound can be useful in designing novel phenolic lipids with potential applications in cosmetic and biomedical fields.

Abstract
The synthesis of five novel methyl 10-undecenoate-based lipoconjugates of phenolic acids from undecenoic acid was carried out. Undecenoic acid was methylated to methyl 10-undecenoate which was subjected to a thiol–ene reaction with cysteamine hydrochloride. Further amidation of the amine was carried out with different phenolic acids such as caffeic, ferulic, sinapic, coumaric and cinnamic acid. All synthesized compounds were fully characterized and their structures were confirmed by spectral data. The anti-oxidant activity of the synthesized lipoconjugates of phenolic acids was studied by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay and also by the inhibition of linoleic acid oxidation in micellar medium by differential scanning calorimetry (DSC). The prepared compounds were also screened for their cytotoxic activity against five cell lines. It was observed that the lipoconjugates of caffeic acid, sinapic acid, ferulic acid, and coumaric acid displayed anticancer and anti-oxidant properties. The anticancer properties of these derivatives have been assessed by their IC50 inhibitory values in the proliferation of MDA-MB231, SKOV3, MCF7, DU 145 and HepG2 cancer cell lines.
