Abstract
Amphipathicity is a critical characteristic of helical antimicrobial peptides (AMPs). The hydrophilic region, primarily composed of cationic residues, plays a pivotal role in the initial binding to negatively charged components on bacterial membranes through electrostatic interactions. Subsequently, the hydrophobic region interacts with hydrophobic components, inducing membrane perturbation, ultimately leading to cell death, or inhibiting intracellular function. Due to the extensive diversity of natural and synthetic AMPs with regard to the design of amphipathicity, it is complicated to study the structure-activity relationships. Therefore, this work aims to categorize the common amphipathic design and investigate their impact on the biological properties of AMPs. Besides, the connection between current structural modification approaches and amphipathic styles was also discussed.

Abstract
RNA therapeutics is an innovative and rapidly evolving field at the forefront of medical research and biotechnology. Recently, many studies have shown that diverse RNA types play important roles in cells. Besides the protein translation coding, they also express and regulate a variety of cellular pathways. Indeed, along with the research and studies, many drugs and vaccines were developed from RNAs, including both coding and non-coding RNA. Some cases were approved to be medicines or under clinical trial. After years of use and application, they have shown a bright opportunity to prevent and treat many fatal and rare diseases with many strong points, such as fast production and long-term effects. Besides, they still have some drawbacks that need to be overcome, like stability or delivery to become the new generation of medicine. Therefore, this chapter focuses on providing an overview of the advantages and disadvantages of RNA therapeutics as well as some crucial points for future development.

Abstract
The ability of amphipathic peptides to arrange themselves in aqueous solutions, known as self-assembly, has been found to reduce the effectiveness of these peptides in interacting with cell membranes. Therefore, minimizing their tendency to self-assemble could be a potential strategy for enhancing the pharmacological properties of antimicrobial peptides (AMPs). To explore this idea, this study prepared a series of natural peptides mastoparan C (MPC) with increased net charge and hydrophilicity via alanine-to-lysine substitution and investigated the impact on the biological activity. The preliminary data suggested the influence of both the overall positive charge and the position of a lysine residue on the self-assembly of MPC and its derivatives. Besides, the analogue MPC-A5K,A8K displayed higher anticancer activity and comparable antimicrobial activity with significantly lower hemolysis than MPC. Hence, reducing self-assembly by expanding the cationic area could be a promising approach for developing potent and selective AMPs.
