Recently there has been a resurging interest in developing multi-functional drugs to treat diseases with complex pathological mechanisms. Such drug molecules simultaneously target multiple etiologies that have been found to be important modulators in specific diseases. This approach has significant promise and may be more effective than using one compound specific for one drug target or, by a polypharmaceutical approach, using a cocktail of two or more drugs. Polycyclic ring structures are useful as starting scaffolds in medicinal chemistry programs to develop multi-functional drugs, and may also be useful moieties added to existing structures to improve the pharmacokinetic properties of drugs currently used in the clinic or under development. This review attempts to provide a synopsis of current published research to exemplify the use of polycyclic compounds as starting molecules to develop multi-functional drugs.

The neurovascular unit (NVU) is highly responsible for cerebral homeostasis and its dysfunction emerges as a critical contributor to Alzheimer's disease (AD) pathology. Hence, rescuing NVU dysfunction might be a viable approach to AD treatments. Here, we fabricated a self-regulated muti-functional nano-modulator (siR/PIO@RP) that can intelligently navigate to damaged blood-brain barrier and release therapeutical cargoes for synergetic AD therapy.

The key to the treatment of choroidal melanoma (CM) is to improve diagnostic efficiency and find a high-performance treatment to replace the traditional treatment of radiotherapy and enucleation. In this paper, for the first time, long afterglow luminescence material was applied to the integrated diagnosis and treatment of eyes, with its unique advantages in photoluminescence and afterglow luminescence to solve the bottleneck problem of real-time irradiation required for photothermal and photodynamic therapy (PTT and PDT). Based on the excellent photoluminescence and afterglow properties of ZnGaGeO:CrYbEr (ZGGO) nanoparticles, a nanoplatform ZGGO@Au@UiO-66@ZnPc:Dox-FA (GAUZD-FA) for NIR-Ⅱ imaging and triple-synergistic therapy (PTT, PDT and sustained-release drug) was constructed.

A promising new approach to mitigate the adverse effects of chemotherapeutic drugs on healthy tissues involves combining sonodynamic therapy with topical chemotherapy to enhance the therapeutic efficacy of anticancer drugs. In this study, we introduce a multi-functional in situ chitosan hydrogel (CS) containing silk fibroin nanoparticles (SFNPs) loaded with doxorubicin (DOXSFNPs) and CuO/TiO nanoparticles (CTNPs) for combination therapy. The developed DOXSFNPs exhibited a size of 257 ± 6 nm, a zeta potential of -14.

While many researchers can design knockdown and knockout methodologies to remove a gene product, this is mainly untrue for new chemical inhibitor designs that empower multifunctional DNA Damage Response (DDR) networks. Here, we present a robust Goldilocks (GL) computational discovery protocol to efficiently innovate inhibitor tools and preclinical drug candidates for cellular and structural biologists without requiring extensive virtual screen (VS) and chemical synthesis expertise. By computationally targeting DDR replication and repair proteins, we exemplify the identification of DDR target sites and compounds to probe cancer biology.
