Pancreatic tumors are hypovascular, which leads to a poor nutrient supply to support the aggressively proliferating tumor cells. However, human pancreatic cancer cells have extreme resistance to nutrition starvation, which enables them to survive under severe metabolic stress conditions within the tumor microenvironment, a phenomenon known as "austerity" in cancer biology. Discovering agents which can preferentially inhibit the cancer cells' ability to tolerate starvation conditions represent a ...

Abstract A methanolic extract of Thai Piper ribesoides showed preferential cytotoxicity against PANC-1 human pancreatic cancer cells under a nutrient-deprived condition, with a PC50 value of 24 μg/mL. Phytochemical investigation of this bio-active extract led to the isolation of six compounds (1–6), including two new polyoxygenated cyclohexane derivatives, named ribesoidones A and B (1 and 2). The structural elucidation of the new compounds was achieved by a combination of HREIMS, NMR, and circu...

Ethanolic extract of Nelumbo nucifera petals showed preferential cytotoxic activity against HeLa human cervical cancer cell line with a PC50 value of 10.4 μg/mL. This active extract was subjected to a phytochemical investigation study which led to the isolation of nine benzylisoquinoline alkaloids (1-9). The isolated compounds exhibited potent antiausterity activities. Moreover, under nutrient-deprived conditions, (-)-lirinidine (8) induced remarkable alterations in HeLa cell morphology includin...

The antiausterity strategy is a promising approach for the discovery of lead compounds with unprecedented anticancer activities by targeting the tolerance of cancer cells to nutrition starvation. These agents are selectively cytotoxic under the tumor microenvironment-mimicking condition of nutrition starvation, without apparent toxicity in the normal nutrient-rich condition. In this study, an ethanol extract of Betula alnoides showed antiausterity activity against PANC-1 human pancreatic cancer ...

Abstract An ethanolic extract of Derris scandens flowers showed potent preferential cytotoxicity against PANC-1 human pancreatic cancer cells under nutrient-deprived condition, with a PC50 value of 0.7 μg/mL. Phytochemical investigation of this active extract led to the isolation of four prenylated isoflavones (1–4) including a new compound named 4′-O-methylgrynullarin (1). The structure elucidation of the new compound was achieved by HRFABMS and NMR spectroscopic analysis. The isolated compound...

Human pancreatic tumor cells have an intrinsic ability to tolerate nutrition starvation and survive in the hypovascular tumor microenvironment, the phenomenon termed as “austerity”. Searching for an agent that inhibits such tolerance to nutrient starvation and kills the pancreatic cancer cells preferentially in nutrient-starvation is a unique anti-austerity strategy in anti-cancer drug discovery. In this strategy, plant extracts and compounds are tested against PANC-1 human pancreatic cancer cel...

Abstract Phytochemical investigation of the ethanolic extract of Anneslea fragrans twigs resulted the isolation of two new highly-oxygenated and sterically hindered spiro-biflavanoids, named fragranols B and C (1 and 2), together with a known compound 3-epilarixinol (3). The structural elucidation was achieved by HRFABMS, NMR spectroscopic analysis, and quantum ECD calculations. A plausible biogenetic pathway of the isolated compounds is also proposed.

Human pancreatic tumor cells such as PANC-1 are known for their ability to tolerate nutrient starvation and thrive under the hypovascular tumor microenvironment, a phenomenon termed as 'austerity'. A search of agents that preferentially inhibit the cancer cell viability under the starvation condition without toxicity in the nutrient-rich condition is a promising approach in anticancer drug discovery. In this study, a triterpene lactone, 3β-hydroxy-13,28-epoxyurs-11-en-28-one (ursenolide), isolat...
