Despite much progress in cancer therapy, conventional chemotherapy can cause poor biodistribution and adverse side-effects on healthy cells. Currently, various strategies are being developed for an effective chemotherapy delivery system. Silk fibroin (SF) is a natural protein used in a wide range of biomedical applications including cancer therapy due to its biocompatibility, biodegradability, and unique mechanical properties. In this study, SF-coated liposomes (SF-LPs) were prepared as a biomimetic drug carrier. Physicochemical properties of SF-LPs were characterized by Fourier-transform infrared spectroscopy (FTIR), dynamic light scattering, zeta potential measurement, and transmission electron microscopy (TEM). In vitro release of SF-LPs loaded with doxorubicin (DOX-SF-LPs) was evaluated over 21 days. Anticancer activity of DOX-SF-LPs was determined against MCF-7 and MDA-MB231 cells using the MTT assay. SF-LPs containing 1% SF exhibited favorable characteristics as a drug carrier. SF coating modified the kinetics of drug release and reduced the cytotoxic effect against L929 fibroblasts as compared to the uncoated liposomes containing cationic lipid. DOX-SF-LPs showed anticancer activity against breast cancer cells after 48 h or 72 h at 20 μM of DOX. This approach provides a potential platform of long-term release that combines biocompatible SF and phospholipids for cancer therapy, achieving efficient drug delivery and reducing side-effects.

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.

In this study, we prepared PTX-loaded mesoporous hollow SnO2 nanofibers conjugated with folic acid (SFNFP) for liver cancer therapy. According to SEM and TEM characterization, SFNF showed a mesoporous hollow structure. The average outer diameter was 200 nm, and the wall thickness was 50 nm. The DSC and XRD study showed that PTX in the channels of nanofibers was present in an amorphous state. The in vitro release experiments demonstrated that SFNF could efficiently improve the dissolution rate of PTX. Both in vitro cell experiments and in vivo antitumor experiments showed that SFNFP could efficiently inhibit the growth of liver cancer cells. Therefore, SFNF is a promising targeting antitumor drug delivery carrier.

With the improvement in cancer survival, long-term cardiotoxicity has become an area of increased interest. Various cancer therapies, including chemotherapy and radiation therapy can lead to cardiac toxicities with both acute and chronic manifestations. Awareness and early recognition can lead to improvement in cardiac survival and patient outcomes. The focus of this review is to summarize the cancer therapy agents most often associated with cardiovascular side effects, highlighting their mechanism of action and strategies for surveillance and prevention.

Drug resistance and toxicity constitute challenging hurdles for cancer therapy. The application of nanotechnology for anticancer drug delivery is expected to address these issues and bring new hope for cancer treatment. In this context, we established an original nanomicellar drug delivery system based on an amphiphilic dendrimer (AmDM), which could generate supramolecular micelles to effectively encapsulate the anticancer drug doxorubicin (DOX) with high drug-loading capacity (>40%), thanks to the unique dendritic structure creating large void space for drug accommodation. The resulting AmDM/DOX nanomicelles were able to enhance drug potency and combat doxorubicin resistance in breast cancer models by significantly enhancing cellular uptake while considerably decreasing efflux of the drug. In addition, the AmDM/DOX nanoparticles abolished significantly the toxicity related to the free drug. Collectively, our studies demonstrate that the drug delivery system based on nanomicelles formed with the self-assembling amphiphilic dendrimer constitutes a promising and effective drug carrier in cancer therapy.

Background: Natural products are the rootstock for identifying new drugs since ancient times. In comparison with synthetic drugs, they have abounding beneficial effects in bestowing protection against many diseases, including cancer. Cancer has been observed as a major threat in recent decades, and its prevalence is expected to increase over the next decades. Also, current treatment methods in cancer therapy such as radiation therapy and chemotherapy cause severe adverse side effects among the cancer population. Therefore, it is exigent to find a remedy without any side effects. Methods: In recent years, research has focused on obtaining naturally derived products to encounter this complication. The current pace of investigations, such as gene identification and advancement in combinatorial chemistry, leads to the aberrant access to a wide range of new synthetic drugs. In fact, natural products act as templates in structure predictions and synthesis of new compounds with enhanced biological activities. Results: Recent developments in genomics have established the importance of polymorphism, which implies that patients require different drugs for their treatment. This demands the discovery of a large number of drugs, but limited sources restrict the pharmaceutical industry to overcome these major obstacles. The use of natural products and their semisynthetic and synthetic analogues could alleviate these problems. However, the lack of standardization in terms of developing methods for evaluating the chemical composition, efficacy, isolation and international approval is still a major limitation in this field. In the past few years, several drug-approval authorities, including the FDA and WHO have allowed using these naturally derived compounds in humans. Conclusion: In this review, we described the use of some natural products from plant and marine sources in cancer treatment and shed some light on semi-synthetic and synthetic compounds derived from natural sources used in cancer therapy.
