Epilepsy is one of the most common neurological disorder affecting up to 1% of the world population. It is a heterogeneous disorder and includes genetic, structural, metabolic causes, sometimes reason is unknown. In recent 20 years inflammation has been considered as a possible etiologic factor in angiogenesis and epileptogenesis in experimental models but there is still lack of evidence if inflammation could be seen in clinical cases of children with different forms of epilepsy.

Folate-targeted verrucarin A reduces the number of activated macrophages in a mouse model of acute peritonitis.

Bioorg Med Chem Lett 2021 May 5:128091. Epub 2021 May 5.

Department of Chemistry, Purdue University, West Lafayette IN 47907 USA; Institute for Drug Discovery, Purdue University, West Lafayette IN 47907 USA. Electronic address:

Activated macrophages contribute prominently to the progression and maintenance of almost all inflammatory and autoimmune diseases. Although non-specific elimination of these phagocytes has been shown to treat animal models of inflammatory disease, the same therapies have been compromised by unacceptable toxicities, because they also kill quiescent macrophages in healthy tissues. In the studies below, we exploit upregulation of folate receptor beta (FRβ) on inflammatory (but not resting) macrophages to target a cytotoxic drug selectively to the inflammatory subset of macrophages.

Differential expression and role of miR-200 family in multiple tumors.

Anal Biochem 2021 May 5:114243. Epub 2021 May 5.

Department of Gastroenterology, Affiliated Hospital of Zunyi Medical University, Zunyi, Guizhou, 563000, PR China. Electronic address:

microRNA (miRNA) can maintain the homeostasis of the human by participating in the regulation of cell proliferation, apoptosis, differentiation, and metabolism. During the entire stage of tumorigenesis, miRNA can maintain the heterogeneity of cancer stem cells by regulating the formation and metastasis of the tumor, which leads to chemotherapy resistance. miR-200 family consists of five members, which can regulate the proliferation, invasion, and migration of cancer cells by inhibiting the transcription of downstream genes (including zinc finger E-box binding homeobox 1 and 2, E-cadherin, N-cadherin, transforming growth factor-β, and cancer stem cell related-proteins).

Specific inhibition of oncogenic RAS using cell-permeable RAS-binding domains.

Cell Chem Biol 2021 May 4. Epub 2021 May 4.

United Graduate School of Drug Discovery and Medical Information Sciences, Gifu University, Gifu 501-1193, Japan. Electronic address:

Oncogenic RAS proteins, common oncogenic drivers in many human cancers, have been refractory to conventional small-molecule and macromolecule inhibitors due to their intracellular localization and the lack of druggable pockets. Here, we present a feasible strategy for designing RAS inhibitors that involves intracellular delivery of RAS-binding domain (RBD), a nanomolar-affinity specific ligand of RAS. Screening of 51 different combinations of RBD and cell-permeable peptides has identified Pen-cRaf-v1 as a cell-permeable pan-RAS inhibitor capable of targeting both G12C and non-G12C RAS mutants.

Pharmacological SARM1 inhibition protects axon structure and function in paclitaxel-induced peripheral neuropathy.

Brain 2021 May 8. Epub 2021 May 8.

Disarm Therapeutics, a wholly owned subsidiary of Eli Lilly & Co., Cambridge MA 02142, USA.

Axonal degeneration is an early and ongoing event that causes disability and disease progression in many neurodegenerative disorders of the peripheral and central nervous systems. Chemotherapy-induced peripheral neuropathy (CIPN) is a major cause of morbidity and the main cause of dose reductions and discontinuations in cancer treatment. Preclinical evidence indicates that activation of the Wallerian-like degeneration pathway driven by SARM1 is responsible for axonopathy in CIPN. Read More

A Pharmacological and Clinical Overview of Oral Semaglutide for the Treatment of Type 2 Diabetes.

Drugs 2021 May 8. Epub 2021 May 8.

Steno Diabetes Center Copenhagen, Gentofte Hospital, University of Copenhagen, 2900, Gentofte, Denmark.

Oral semaglutide (Rybelsus) is a glucagon-like peptide-1 (GLP-1) receptor agonist (GLP-1RA) with 94% homology to human GLP-1. It is the first GLP-1RA developed for oral administration, and it comprises a co-formulation of the peptide semaglutide with the absorption enhancer sodium N-(8-[2-hydroxybenzoyl] amino) caprylate, which overcomes the challenges of peptide absorption in the acidic conditions of the stomach. Oral semaglutide is indicated for use as an add-on combination therapy (with other glucose-lowering agents, including insulin) or as a monotherapy (in patients who are intolerant to metformin) for type 2 diabetes when diet and exercise do not provide adequate glycemic control.

Gastric Cancer 2021 May 8. Epub 2021 May 8.

Department of Surgery and Science, Graduate School of Medical Sciences, Kyushu University, 3-1-1 Maidashi, Higashi-ku, Fukuoka, 812-8582, Japan.

Background: CD44 variant 9 (CD44v9) has been reported to suppress reactive oxygen spices (ROS) in association with antioxidant factors such as glutathione (GSH) and glutathione peroxidase 2 (GPx2), resulting in promoted tumor growth.

Methods: CD44v9 and GPx2 expression were investigated by immunohistochemistry in resected specimens from 193 gastric cancer (GC) patients without preoperative chemotherapy and in pretreatment biopsy specimens from 29 GC patients with preoperative chemotherapy. We analyzed the relationship between CD44v9 expression and clinicopathological factors, prognosis, and pathological response to chemotherapy. Read More

A Programmed Cell-Mimicking Nanoparticle Driven by Potato Alkaloid for Targeted Cancer Chemoimmunotherapy.

Adv Healthc Mater 2021 May 8:e2100311. Epub 2021 May 8.

Medical Research Institute, College of Pharmaceutical Sciences, Southwest University, Chongqing, 400715, China.

Membrane camouflaged-nanoparticles (CM-NPs) have been exploited to inherit desired functionalities from source cells. Despite those advantages, membrane cloak may play a "double-edged sword" role in tumor-targeting therapy, as the intact membrane coating may hinder function-exertion of loaded drugs after reaching predetermined site. Therefore, further optimization of CM-NPs is still needed to enhance their delivery efficiency. Read More
