Abstract
Administration of monoclonal antibodies (mAbs) is currently focused on subcutaneous injection associated with increased patient adherence and reduced treatment cost, leading to sustainable healthcare. The main bottleneck is low volume that can be injected, requiring highly concentrated mAb solutions. The latter results in increased solution viscosity with pronounced mAb aggregation propensity because of intensive protein-protein interactions. Small molecule excipients have been proposed to restrict the protein-protein interactions, contributing to reduced viscosity. The aim of the study was to discover novel compounds that reduce the viscosity of highly concentrated mAb solution. First, the chemical space of proline analogs was explored and 35 compounds were determined. Viscosity measurements revealed that 18 proline analogs reduced the mAb solution viscosity similar to or more than proline. The compounds forming both electrostatic and hydrophobic interactions with mAb reduced the viscosity of the formulation more efficiently without detrimentally effecting mAb physical stability. A correlation between the level of interaction and viscosity-reducing effect was confirmed with molecular dynamic simulations. Structure rigidity of the compounds and aromaticity contributed to their viscosity-reducing effect, dependent on molecule size. The study results highlight the novel proline analogs as an effective approach in viscosity reduction in development of biopharmaceuticals for subcutaneous administration.

Abstract
We have prepared three alkaloids from the Agelas sponges, clathrodin, hymenidin and oroidin, and a series of their synthetic analogues, and evaluated their inhibitory effect against six isoforms of the Kv1 subfamily of voltage-gated potassium channels, Kv1.1-Kv1.6, expressed in Chinese Hamster ovary (CHO) cells using automated patch clamp electrophysiology assay. The most potent inhibitor was the (E)-N-(3-(2-amino-1H-imidazol-4-yl)allyl)-4,5-dichloro-1H-pyrrole-2-carboxamide (6g) with IC50 values between 1.4 and 6.1 μM against Kv1.3, Kv1.4, Kv1.5 and Kv1.6 channels. All compounds tested displayed selectivity against Kv1.1 and Kv1.2 channels. For confirmation of their activity and selectivity, compounds were additionally evaluated in the second independent system against Kv1.1-Kv1.6 and Kv10.1 channels expressed in Xenopus laevis oocytes under voltage clamp conditions where IC50 values against Kv1.3-Kv1.6 channels for the most active analogues (e.g. 6g) were lower than 1 μM. Because of the observed low sub-micromolar IC50 values and fairly low molecular weights, the prepared compounds represent good starting points for further optimisation towards more potent and selective voltage-gated potassium channel inhibitors.

Abstract
2-Aminoimidazole skeleton represents a unique building block which is often used in the design of modulators of different targets and small molecule drugs. Alkaloids isolated from marine sponges are known to be one of the most common sources of the 2-aminoimidazole compounds and from a medicinal chemistry perspective, the marine alkaloids' fascinating structures as well as their broad spectrum of pharmacological activity make them promising lead compounds for various druggable targets. This review will focus on the presentation of biologically evaluated 2-aminoimidazole compounds showing a variety of pharmacological properties and their structure-activity relationship. The importance of 2-aminoimidazoles as bioisosteres of guanidine, acylguanidine, benzamidine and triazole groups will be highlighted.

Abstract
Marine organisms produce secondary metabolites that may be valuable for the development of novel drug leads as such and can also provide structural scaffolds for the design and synthesis of novel bioactive compounds. The marine alkaloids, clathrodin and oroidin, which were originally isolated from sponges of the genus, Agelas, were prepared and evaluated for their antimicrobial activity against three bacterial strains (Enterococcus faecalis, Staphylococcusaureus and Escherichiacoli) and one fungal strain (Candida albicans), and oroidin was found to possess promising Gram-positive antibacterial activity. Using oroidin as a scaffold, 34 new analogues were designed, prepared and screened for their antimicrobial properties. Of these compounds, 12 exhibited >80% inhibition of the growth of at least one microorganism at a concentration of 50 µM. The most active derivative was found to be 4-phenyl-2-aminoimidazole 6h, which exhibited MIC90 (minimum inhibitory concentration) values of 12.5 µM against the Gram-positive bacteria and 50 µM against E. coli. The selectivity index between S. aureus and mammalian cells, which is important to consider in the evaluation of a compound’s potential as an antimicrobial lead, was found to be 2.9 for compound 6h.
