It is important that future efforts focus on delineating all the steps of the molecular mechanism that implicates ALR2 in inflammatory pathologies. At the same time, utilizing the previous efforts in the field of ARIs, several candidates that have been proven safe in the clinic may be evaluated for their clinical significance as anti-inflammatory medication. Finally, structurally novel ARIs, designed to target specifically the proinflammatory subpocket of ALR2, should be pursued.

Undoubtedly, efficient cancer treatment has been a significant challenge for the scientific community over the last decades. Despite tremendous progress made towards this direction, there are still efforts needed to discover new anticancer drugs. In this work, a series of N-substituted pyrrolebased scaffolds have been synthesized and evaluated for antiproliferative activity against a panel of cancer cell lines (L1210, CEM and HeLa). Furthermore, in order to discover new scaffolds as antiviral agents, all the examined compounds were evaluated for activity against different types of DNA and RNA viruses. The key feature of the above structures is the existence of an aromatic ring with at least one hydrogen-bonding donor and acceptor group. Results have shown noteworthy cytostatic activity for three of the synthesized compounds (1, 3 and 9). Especially, compound 1, containing a tropolone ring, proved to be the most promising scaffold (IC50:10-14 µM) for the development of novel potential anticancer agents. In addition, compound 1 has shown modest anti-HSV-1, -HSV2 activity in HEL cell cultures (EC50: 27-40 µM).

TransferRNA's role in protein translation is the prime example of an Informational Leaving Group (ILG). A simplified model produced oligophenylalanine with a modified uracil as an ILG in the presence of specific oligonucleotides. Our preliminary studies contribute to the importance of hybrid species in bridging the gap between peptides and nucleic acids.
