Researchers from Osaka University and Dusseldorf University have found a new theranostic compound that effectively shrinks prostate tumor in mice. Theranostics is a cancer treatment that involves finding cancer cells anywhere in the body and delivering targeted radiation to kill those cells, by drugs that contain radioactive isotopes. It means that this compound could be a promising option for treating hormone-resistant metastases in patients with recurrent cancers. This is stated to be tested in an upcoming clinical trial.

A research group at Osaka Metropolitan University has developed a drug delivery system that activates a strong cellular immune response to attack cancer cells, using one-tenth of the amount of antigen needed in the group’s previous work. By incorporating positively charged cationic lipids into liposomes and adding negatively charged pH-responsive polysaccharides to the surface, the research group increased the uptake efficiency of liposomes encapsulating cancer antigens by dendritic cells by approximately five times, which increased cytokine production by about 100 times. This increased M1-type macrophages, which activate cancer immunity, and decreased M2-type macrophages, which promote cancer growth.

Broccoli may contain advantages beyond nutrition. A molecule found in broccoli, cabbage and more digests down into DIM, a compound with brighter benefits than the name implies, such as inducing cell death in breast, prostate and colon cancer. Now, researchers are beginning to understand the mechanism underpinning this molecular behavior — information that could help elucidate future anti-cancer treatments.

Researchers from Osaka City University have shown in mice models of Alzheimer's disease, frontotemporal dementia, and dementia with Lewy bodies, that the intranasal administration of rifampicin and resveratrol in combination is safer and improves cognitive function more than rifampicin alone. The research results are expected to lead to the development of safe and effective nasal spray for the prevention of dementia.

Researchers at Kanazawa University describe in Scientific Reports the identification of small compounds that can regulate the cellular production of extracellular vesicles — nanocontainers transporting biomolecules between cells. Such compounds hold promise for use in therapies for various diseases.

A stress response of mitochondria, the part of our cells that produce energy to power bodily functions, is important to a longer life. A team of scientists from Osaka City University, Japan, searched through a chemical “library” of existing drugs to find one that can activate this stress response in the worm Caenorhabditis elegans. They found that an anti-hypertension drug called metolazone prolongs C. elegans lifespan, marking the first step in developing anti-aging pharmaceuticals.

Researchers from the University of Tsukuba demonstrate that the hypnotic and teratogenic effects of thalidomide are separable. Thalidomide is a medication with several different effects, one of which is promoting sleep in the context of insomnia. In a new study, researchers from the University of Tsukuba have discovered that thalidomide exerts its hypnotic effects through mechanisms distinct from those for the drug’s notorious teratogenicity. These are striking results showing how thalidomide induces sleep independently of its known effects on the teratogenic cereblon pathway. These findings could be helpful in developing novel thalidomide-like hypnotic drugs without thalidomide’s teratogenic effects. The study was published in the scientific journal Proceedings of the National Academy of Sciences of the United States of America.

Drugs tackling chronic myelogenous leukemia have completely transformed prognoses of patients over the last couple of decades, with most cases going into remission. But drug resistance can occur, leading to relapses. Targeting the lipids involved in regulating part of a leukemia stem cell’s life span offers a potential second route to defeat the disease—and solid tumorous cancers as well.

Dr Kwa is currently a Pharmacy Clinician Scientist and Assistant Director, Pharmacy (Research), at the Singapore General Hospital. She specializes in critical care medicine, infectious diseases and antimicrobial resistance research.
My research background covers multidisciplinary fields such as Pharmaceutics, Cancer Nanomedicine, Bioengineering and Organ-on-a-chip platforms. My current research focuses on the development of dynamic biological barriers on a chip such as blinking human cornea on a chip.
Giants in history
Japanese chemist Takamine Jokichi (3 November 1854 – 22 July 1922) founded the Tokyo Artificial Fertilizer Company, where he isolated a starch-digesting enzyme (named takadiastase) from the fungus Aspergillus oryzae.
The research of Filipino pharmaceutical chemist Luz Oliveros-Belardo (3 November 1906 – 12 December 1999) focussed on essential oils and other chemicals derived from native Philippine plants.
Filipina chemist María Orosa (29 November 1892–13 February 1945) fought malnutrition and food insecurity in the Philippines by devising over 700 culinary creations including Soyalac, a nutrient rich drink made from soybeans, and Darak, rice cookies packed with Vitamin B1, which could prevent beriberi disease caused by Vitamin B1 deficiency. She was also a partisan of the guerrilla movement resisting Japanese occupation during World War II, and died after being struck by shrapnel while working in her laboratory during the Battle of Manila.
Filipino chemist and pharmacist Manuel A. Zamora (29 March 1870 – 9 July 1929) is best remembered for his discovery of the tiki-tiki formula to combat beriberi, a disease caused by Vitamin B1 deficiency.
