Oncolytic viruses (OVs) form a group of novel anticancer therapeutic agents which selectively infect and lyse cancer cells. Members of several viral families, including Picornaviridae, have been shown to have anticancer activity. Picornaviruses are small icosahedral non-enveloped, positive-sense, single-stranded RNA viruses infecting a wide range of hosts. They possess several advantages for development for cancer therapy: Their genomes do not integrate into host chromosomes, do not encode oncogenes, and are easily manipulated as cDNA. This review focuses on the picornaviruses investigated for anticancer potential and the mechanisms that underpin this specificity.

Cancer, a highly heterogeneous disease at intra/inter patient levels, is one of the most serious threats to human health across the world [1, 2]. Notwithstanding the noteworthy advances in its treat-ment, the morbidity and mortality of cancer are projected to grow for a long period, and the global cancer burden is expected to be 28.4 million cases in 2040, a 47% rise from 2020 [3]. Accordingly, there is a constant need to explore novel anticancer agents. <p> There are several strategies to discover novel anticancer candidates: (1) new lead hits or candidates from natural resources [4] whichexhibit various biological properties and are a rich source of com-pounds in drug discovery due to the structural and mechanistic diversity, and more than 60% anti-cancer agents can be traced to a natural product; (2) Molecular hybridization is one of the most prom-ising strategies for the discovery of novel anticancer drug candidates since hybrid molecules have the potential to bind multiple targets or to enhance the effect through acting with another bio-target or to counterbalance the side effects caused by the other part of the hybrid [5]; (3) Dimerization is a useful tool to develop novel anticancer drug candidates with enhanced biological activity, reduced side effects and improved pharmacokinetic profiles [6]; (4) Drug repurposing strategy is is an attractive strategy and has been approved, along with non-anticancer macrolide drugs for the treatment of cancer, for anticancer drug discovery since toxicity and pharmacokinetic profiles have already been estab-lished [7]. <p> Heterocycles coumarin, β-lactone, macrolide and triazole are useful anticancer pharmacophores since their derivatives could exert the anticancer activity through diverse mechanisms, inclusive of inhibition of aromatase, carbonic anhydrase, ki-nase, P-glycoprotein, sulfatase, telomerase, vascular endothelial growth factor receptor 2 and tubulin [8-11]. In particular, nat-ural-derived coumarin, β-lactone and macrolide derivatives are important sources of new anticancer lead hits/candidates; mac-rolide repurposed drugs can circumvent high cost and long-time associated with traditional drug discovery strategies; couma-rin, β-lactone and macrolide hybrids as well as bis-triazole compounds have the potential to enhance the anticancer activity, overcome drug resistance, reduce the side effects and improve pharmacokinetic profiles.

Bile Acid Profiles

Bile acids control lipid homeostasis by regulating uptake from food and excretion. Additionally, bile acids are bioactive molecules acting through receptors and modulating various physiological processes. Impaired bile acid homeostasis is associated with several diseases and drug-induced liver injury. Individual bile acids may serve as disease and drug toxicity biomarkers, with a great demand for improved bile acid quantification methods. We developed, optimized, and validated an LC-MS/MS method for quantification of 36 bile acids in serum, plasma, and liver tissue samples. The simultaneous quantification of important free and taurine- and glycine-conjugated bile acids of human and rodent species has been achieved using a simple workflow. The method was applied to a mouse model of statin-induced myotoxicity to assess a possible role of bile acids. Treatment of mice for three weeks with 5, 10, and 25 mg/kg/d simvastatin, causing adverse skeletal muscle effects, did not alter plasma and liver tissue bile acid profiles, indicating that bile acids are not involved in statin-induced myotoxicity. In conclusion, the established LC-MS/MS method enables uncomplicated sample preparation and quantification of key bile acids in serum, plasma, and liver tissue of human and rodent species to facilitate future studies of disease mechanisms and drug-induced liver injury.

Exosomes are a class of extracellular vesicles, with a size of about 100 nm, secreted by most cells and carrying various bioactive molecules such as nucleic acids, proteins, and lipids, and reflect the biological status of parent cells. Exosomes have natural advantages such as high biocompatibility and low immunogenicity for efficient delivery of therapeutic agents such as chemotherapeutic drugs, nucleic acids, and proteins. In this review, we introduce the latest explorations of exosome-based drug delivery systems for cancer therapy, with particular focus on the targeted delivery of various types of cargoes.

AbstractBile acids are abundantly present in the mammalian gut, where they undergo bacteria-mediated transformation, generating a large pool of bioactive molecules. While they have been shown to affect host metabolism, cancer progression and innate immunity, it is unknown whether bile acids affect the function of adaptive immune cells such as T cells expressing IL-17a (Th17 cells) and regulatory T cells (Tregs) that mediate inflammatory and anti-inflammatory responses, respectively. By screening a small-molecule library primarily composed of bile acid metabolites, we identified two distinct derivatives of lithocholic acid (LCA), 3-oxoLCA and isoalloLCA, as specific regulators of Th17 and Treg cells. While 3-oxoLCA inhibited Th17 cell differentiation by directly binding to its key transcription factor RORγt (retinoid-related orphan receptor γ t), isoalloLCA enhanced differentiation of Tregs through mitochondrial-dependent metabolic changes, leading to an increased expression of Foxp3. IsoalloLCA-dependent Treg enhancement required an intronic Foxp3 enhancer, the conserved noncoding sequence 3 (CNS3), which acts as an epigenetic switch that confers a poised state to the Foxp3 promoter. Lastly, oral administration of 3-oxoLCA and isoalloLCA to mice led to reduced Th17 and increased Treg cell differentiation in the intestinal lamina propria. Altogether, our data suggest novel mechanisms by which bile acid metabolites control host immune responses by directly modulating the Th17 and Treg balance.

: Breast cancer is the most common invasive cancer in women, and the second main cause of deaths in women, after lung cancer. There is continuous advancement in the development of therapeutic agents against breast cancer in recent years and it is still in progress. Development of hybrid molecules by combining different pharmacophores to obtain significant biological activity is an excellent approach. Coupling of coumarin scaffold with other distinct motifs has led to the design of newer compounds against breast cancer. These distinct pharmacophores possess a diverse mode of action as well as selectivity. It has been reported in the literature that coumarin hybrids possess significant potency against breast cancer by binding to various biological targets which are associated with breast cancer. Due to low toxicity profile on various organ systems, coumarin hybrids have nowadays attracted the keen attention of researchers to explore their therapeutic ability against breast cancer. Reported coumarin hybrids include coupling with isoxazole, thiazole, monastrol, chalcone, triazole, sulphonamide, triphenylethylene, benzimidazole, pyran, imidazole, stilbene, oestrogen, phenylsulphonylfuroxan, etc. In the present review, a description of various coumarin hybrid molecules has been presented along with their structural-activity relationships.
