Diglycerides of Natural Phenols and Organic Acids for Enhanced Biological Activities
Asian Journal of Organic Chemistry, EarlyView.Diglycerides of natural organic acids and phenols were synthesized regio‐selectively. Diglycerides are structurally similar to cell membranes and are expected to exhibit cell affinity and permeability. The flexible glycerol linkers allow the diglycerides to exhibit not only the physiological activities of each constituent organic acid but also the ...

Nle4DPhe7α-Melanocyte-Stimulating Hormone Increases the Eumelanin:Phaeomelanin Ratio in Cultured Human Melanocytes [PDF]
, 1995 In mammals, melanin exists in two chemically distinct forms: the red-yellow phaeomelanin and the brown-black eumelanin. Although administration of the pigmentary hormone α-melanocyte-stimulating hormone (αMSH) and its synthetic analogue Nle4DPhe7αMSH ...

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)
The Anatomical Record, EarlyView.Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

Fine‐Tuning NIR‐Absorbing BODIPYs for Photoacoustic Detection of Hypochlorous Ion (OCl−)
Chemistry – An Asian Journal, Volume 20, Issue 6, March 17, 2025.High selectivity for hypochlorous ion over other competing reactive oxygen species was achieved by optimizing different regioisomers of conjugation‐extended, near‐infrared‐absorbing BODIPYs for photoacoustic imaging. Abstract Highly reactive oxygen and nitrogen species (ROS/RNS) play crucial roles in various pathological conditions.

Paxilline negative mutants of Penicillium paxilli generated by heterologous and homologous plasmid integration : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Molecular Genetics at Massey University, Palmerston North, New Zealand [PDF]
, 1998 Using a monoclonal antibody-based ELISA, 600 pAN7-1 plasmid-tagged mutants of Penicillium paxilli were screened for paxilline accumulation and one paxilline negative mutant, YI-20, was identified (Itoh, unpublished data).
