Antifungals for Host-Directed Antiviral Therapy
Because of their epidemic and pandemic potential, emerging viruses are a major threat to global healthcare systems. While vaccination is in general a straightforward approach to prevent viral infections, immunization can also cause escape mutants that hide from immune cell and antibody detection. Thus, other approaches than immunization are critical for the management and control of viral infections. Viruses are prone to mutations leading to the rapid emergence of resistant strains upon treatment with direct antivirals. In contrast to the direct interference with pathogen components, host-directed therapies aim to target host factors that are essential for the pathogenic replication cycle or to improve the host defense mechanisms, thus circumventing resistance. These relatively new approaches are often based on the repurposing of drugs which are already licensed for the treatment of other unrelated diseases.

Antifungals in Preventing Oropharyngeal Candidiasis among HIV-Infected Adults
Oropharyngeal candidiasis (OPC) is attributed to the overgrowth of the commensal fungi, Candida spp., in the mouth and throat. Among HIV-infected adults, there is an increased risk of developing OPC due to the loss of cell-mediated immunity. Fluconazole can be considered as an effective agent with a better safety profile for the prevention of OPC in HIV-infected adults.

Antigen Targeted Therapy for LS
Lynch syndrome (LS) and constitutional mismatch repair deficiency (CMMRD) are hereditary disorders which significantly increase a person’s risk of developing a variety of cancers such as colorectal, endometrial, brain and, for CMMRD also, haematological malignancies. This increased cancer risk is due to inherited mutations in specific types of DNA repair genes, which hampers repair of mispaired or damaged bases during DNA replication. As a consequence, somatic mutations rapidly accumulate and typically include insertions and deletions (indels) in microsatellites that potentially can give rise to neoantigens. These neoantigens open up avenues for neoantigen-targeting immune therapies.

Antigenic Essence
Antigenic essence – the part of a cell that is both available to the immune system and also highly specific to cell type on a molecular profile level. Antigenic essence can be collected from the cell surface by treating living cells with protease (trypsin) under mild conditions. Cells are a natural source for the entire diversity of native antigens including for anticancer vaccination. Antigenic essence takes advantage of this while also minimizing the limitations associated with the use of whole cells for anticancer vaccination.

Antihypertensives’ around the Clock
Although homeostasis is a commonly accepted concept, there is incontrovertible evidence that biological processes and functions are variable, and that variability occurs in cycles. So allostatic model has emerged as the first challenge to homeostasis. Circadian variation is the predominant variation in the body. As there is strong scientific and clinical evidence that blood pressure fluctuations undergo circadian rhythm, there is equally strong evidence that targeted time therapy for hypertension provides a better outcome of the disease. The research has gone even further by ensuring better patients' adherence throughout the development and approval process for the use of pulsatile drug release systems which can be considered as an option for an even more convenient dosage regimen of the medicines needed.

Antimetabolite Drug
Methotrexate (4-{N-[(2,4-diaminopteridin-6-yl) methyl]-N-methylamino} benzoyl)-L-glutamic acid, MTX) is an antimetabolite drug. It is widely used as a chemotherapeutic agent in rheumatoid arthritis (RA), psoriasis and some sorts of leukemia. MTX is a relatively well-known molecule and is a first-line antirheumatic medication because of its efficacy and safety. It decreases the concentration of tetrahydrofolate (THF) in the cells by the inhibition of dihydrofolate reductase (DHFR) enzyme, therefore it reduces the purine nucleotide and DNA synthesis.

Antimicrobial and Antibiofilm Activities of Rosmarinic Acid
Rosmarin is an original plant compound listed among the hydroxycinnamic acids. This substance has been widely used to fight microbial pathology and chronic infections from microorganisms like bacteria, fungi and viruses. Also, various derivatives of rosmarinic acid, such as the propyl ester of rosmarinic acid, rosmarinic acid methyl ester or the hexyl ester of rosmarinic acid, have been synthesized chemically, which have been isolated as natural antimicrobial agents. Rosmarinic acid and its derivatives were combined with antibiotics to obtain a synergistic effect.

Antimicrobial Effects of Antimicrobial Peptides
The growing emergence of antimicrobial resistance represents a global problem that not only influences healthcare systems but also has grave implications for political and economic processes. As the discovery of novel antimicrobial agents is lagging, one of the solutions is innovative therapeutic options that would expand our armamentarium against this hazard. Compounds of interest in many such studies are antimicrobial peptides (AMPs), which actually represent the host’s first line of defense against pathogens and are involved in innate immunity. They have a broad range of antimicrobial activity against Gram-negative and Gram-positive bacteria, fungi, and viruses, with specific mechanisms of action utilized by different AMPs.

Antimicrobial Essential Oils
Microbial pathogens are the most prevalent cause of chronic infections and fatalities around the world. Antimicrobial agents including antibiotics have been frequently utilized in the treatment of infections due to their exceptional outcomes. However, their widespread use has resulted in the emergence of multidrug-resistant strains of bacteria, fungi, viruses, and parasites.

Antimicrobial Mediterranean Wild Edible Plants
Mediterranean wild edible plants (MWEPs) and their antimicrobial properties have been known from ancient times, and nowadays, a growing number of people have rediscovered them as natural remedies for common infections. One of the problems concerning their use is the heterogeneity of the protocols used to extract and analyze the properties of their active principles; such heterogeneity still marks the overall set of scientific studies on MWEPs, not to mention the enormous heterogeneity that characterizes the properties of plants at the outset. We reviewed the current literature on medicinal value of Mediterranean native edible plants trying to emphasize both the weaknesses and the opportunities of these plants. The majority of the reviewed MWEPs can inhibit both Gram-negative and Gram-positive bacteria, and fungi.
