OX40 and 5T4 are molecules that play a role in T-cell expansion and cytoskeleton's disruption in cancer, respectively. US2019161555 patent describes a bispecific antibody that targets OX40/5T4 with the potential application of cancer treatment. The method of analysis of the US201916155 patent consisted of claim's analysis, as well as the chemical/biological information's analysis of the bispecific antibody. The patent includes independent claims related to bispecific antibodies that bind to OX40/5T4, DNA encoding the antibodies, a vector that harbors the DNA, a host cell that contains the vector, a pharmaceutical composition containing a pharmaceutically effective amount of the antibodies, medical use of the antibodies, use of the antibodies in the treatment or prevention of neoplastic disorders and a method of treating neoplastic disorders. Bispecific antibodies that target OX40/5T4 can activate IL-2 secretion in CD4+ T cells.

PD-L1 and ICOS are immune control points in cancer and their presence in cancer tends to have a poor prognosis. WO2019122882 patent describes a bispecific antibody that targets PDL-1/ICOS with the potential application of cancer treatment. WO2019122882 patent describes a bispecific antibody with antitumor efficacy in CT26 model through of the depletion of TReg cells and improved ratio of CD8+ T cells: TReg in tumor microenvironment. The anti-PDL-1/ICOS antibody is new; however, only preclinical assays are shown using colon carcinoma model. So far, there are no reports of clinical trials to evaluate the safety, toxicity and efficacy, but it will be of great interest to analyze in the future if this antibody surpasses the action of the combinatorial therapy in cancer.

Antibiotic resistance has become a global health problem requiring urgent intervention. The pace of development and frequency of transmission of antimicrobial resistance have tremendously surpassed the number of antibiotics developed in the past few decades. Emergence and transmission of multidrug-resistant genes, for example, mcr-1 and mcr-5.3, against the last resort of antibiotics has challenged the treatment options. Vaccination is a promising approach with no instance of antimicrobial resistance generation or transmission reported so far. The time required for developing a vaccine, extensive pre- and post-licensure studies and the financial constraints for the R&D has hampered vaccine development over the past few decades. Vaccine can prove to be an effective future strategy for combating antimicrobial resistance.

The use of nanoparticulate systems to diagnose and treat tumors has gained momentum with the rapid development of nanomedicine. Many nanotheranostics fail due to insufficient bioavailability and low accumulation at the tumor site, resulting in undesirable side effects. We describe the use of an engineered hepatitis E viral nanoparticle (HEVNP) with enhanced bioavailability, tissue retention and mucosal penetration capacities. HEVNP is a modular nanocapsule that can encapsulate heterologous nucleotides, proteins and inorganic metals, such as ferrite oxide nanoparticles. Additionally, the exterior protruding arms of HEVNP is composed of loops that are used for chemical coupling of targeting and therapeutic peptides. We propose the use of HEVNP to target colorectal cancer (i.e., polyps) with imaging-guided delivery using colonoscopy.

There is expanding proof that specific natural compounds found in plants have additional conventional medicinal properties. One such compound is xanthohumol (XN), which is being explored as an antimicrobial, anticarcinogenic, antidiabetic and anti-inflammatory agent - aside from its utilization in dealing with conditions like autism, bone and skin improvement and microbial infections, lipid-related illnesses, and so on. XN is reported to suppress the uncontrolled production of inflammatory mediators responsible for diseases including cardiovascular disease, neurodegeneration and tumors. Further, it is accounted to limit adipogenesis and control obesity by focusing on principal adipocyte marker proteins. It is most generally utilized in the brewing industry as an additive and flavoring agent to add bitterness and aroma to beer. Present investigation sum up the patents filed in most recent 2 years on development of different pharmaceutical mixes and strategies dependent on various therapeutic potentials of XN.

The alteration of mRNA translation has a crucial role in defining the changes in cellular proteome. The phosphorylation of eukaryotic initiation factor 4E by mitogen-activated protein kinase-interacting kinases (Mnks) leads to the release and translation of mRNAs of specific oncogenic proteins. In recent years, the efforts made by the pharmaceutical industry to develop novel chemical skeletons to create potent and selective Mnk inhibitors have been fruitful. The pyridone-aminal scaffold has been utilized to generate several series of Mnk inhibitors presented in multiple patent applications and research articles. Tomivosertib (eFT508) is one of the molecules with such scaffold. It is one of the first two Mnk inhibitors that entered clinical trials, and has displayed momentous activity against several solid and hematological cancers. The present compilation provides a succinct review of the current state of development of pyridone-aminal-derived Mnk inhibitors through the analysis of relevant patent applications filed in the last 5 years.

Dengue, an illness caused by four serotypes of the dengue virus is most prevalent in Asia and Latin America. Its manifestation varies from asymptomatic cases to severe forms and even deaths and is a growing health concern. Despite attempts to curtail it, the infection continues to intensify in endemic areas and spread to new areas of the world. Development of a safe and effective vaccine and a potent antiviral drug is ongoing but so far there has been no breakthrough. Nonetheless, researchers are carrying out studies with newer vaccine candidates and antiviral moieties, and some of these hold promise for the future. The current article describes the recent patents targeted at dengue control.
