Non-Steroidal Anti-Inflammatory Drugs
The non-steroidal anti-inflammatory drugs (NSAIDs) are the most used drugs in knee OA (osteoarthritis) treatment. Despite their efficiency in pain and inflammation alleviation, NSAIDs accumulate in the environment as chemical pollutants and have numerous genetic, morphologic, and functional negative effects on plants and animals. Ultrasound (US) therapy can improve pain, inflammation, and function in knee OA, without impact on environment, and with supplementary metabolic beneficial effects on cartilage compared to NSAIDs. These features recommend US therapy as alternative for NSAIDs use in knee OA treatment.

Non-Viral Gene Delivery Systems
Non-viral materials, such as polymers and lipids, have been developed to create ‘synthetic artificial viruses’ for the delivery of genes into cells in vitro and in vivo. Owing to their limitations in overcoming extra- and intracellular obstacles, these synthetic materials can exhibit poor delivery efficiency relative to viral vectors. However, considering their biocompatibility, high loading capacity, facile fabrication, and potential large-scale production, non-viral vectors have shown great progress in the delivery of gene cargos, especially small interfering RNA (siRNA) molecules.

Nonalcoholic Steatohepatitis and Atherosclerosis
Nonalcoholic steatohepatitis (NASH) is the most severe manifestation of nonalcoholic fatty liver disease (NAFLD), a common complication of type 2 diabetes, and may lead to cirrhosis and hepatocellular carcinoma. Oxidative stress and liver cell damage are the major triggers of the severe hepatic inflammation that characterizes NASH, which is highly correlated with atherosclerosis and coronary artery disease.

Nonribosomal Peptide and Polyketide Against Human Pathogens
Antibiotics are majorly important molecules for human health. Following the golden age of antibiotic discovery, a period of decline ensued, characterised by the rediscovery of the same molecules. At the same time, new culture techniques and high-throughput sequencing enabled the discovery of new microorganisms that represent a potential source of interesting new antimicrobial substances to explore.

Novel 1,2,4-Oxadiazole Derivatives
Five-membered 1,2,4-oxadiazole heterocyclic ring has received considerable attention because of its unique bioisosteric properties and an unusually wide spectrum of biological activities. Thus, it is a perfect framework for the novel drug development. After a century since the 1,2,4-oxadiazole have been discovered, the uncommon potential attracted medicinal chemists’ attention, leading to the discovery of a few presently accessible drugs containing 1,2,4-oxadiazole unit. It is worth noting that the interest in a 1,2,4-oxadiazoles’ biological application has been doubled in the last fifteen years. Herein, after a concise historical introduction, we present a comprehensive overview of the recent achievements in the synthesis of 1,2,4-oxadiazole-based compounds and the major advances in their biological applications in the period of the last five years as well as brief remarks on prospects for further development.

Novel Coumarin-Based Inverse Agonists of GPR55
The G-protein coupled receptor 55 (GPR55) was first described in 1999 and is broadly expressed in different areas of the CNS, such as the frontal cortex or the hippocampus. The discovery of the bioactive lipid lysophosphtatidylinositol (LPI) as endogenous GPR55 agonist led to the receptor’s deorphanization . However, besides LPI, several commercially available as well as endogenous ligands show agonistic or antagonistic activity at the GPR55. Endocannabinoids, 2-arachidonoylglycerol, and delta-9-tetrahydrocannabinol (Δ9-THC) for instance, show strong affinities and activation of GPR55, heating up the discussion about GPR55 as potential third cannabinoid-receptor (CB). Commercially available GPR55 agonists, such as O-1602, and GPR55-antagonists like ML-193 are commonly used in GPR55 research, to evaluate GPR55-specific molecular pathways and effects. Besides these widely used GPR55 ligands, coumarin-derivates show antagonistic coupled to inverse agonistic activities on GPR55-dependent neuroinflammatory processes as reported recently.

Novel Fucoidan Pharmaceutical Formulations and Their Potential Application
Fucoidan belongs to a family of sulfated, L-fucose-rich polysaccharides found in the cell wall matrix of various species of marine brown algae (Phaeophyta: Laminariaceae, Fucaceae, Chordariaceae and Alariaceae). Fucoidan can also be obtained from sea cucumbers (Holothuroidea: Stichopodidae, Holothuriidae), sea urchin eggs (Echinoidea: Strongylocentrotidae, Arbaciidae) and sea grasses (Cymodoceaceae).

Novel Pharmacological Targets of Post-Traumatic Stress Disorders
Post-traumatic stress disorder (PTSD) is a psychopathological condition with a heterogeneous clinical picture that is complex and challenging to treat. Its multifaceted pathophysiology still remains an unresolved question and certainly contributes to this issue. The pharmacological treatment of PTSD is mainly empirical and centered on the serotonergic system. Since the therapeutic response to prescribed drugs targeting single symptoms is generally inconsistent, there is an urgent need for novel pathogenetic hypotheses, including different mediators and pathways.
