TOTAL SYNTHESES OF MOKKO LACTONE, DEHYDROCOSTUS LACTONE, AND EREMANTHIN [PDF]

Chemistry Letters, 1984
Abstract A series of guaianolides such as mokko lactone, dehydrocostus lactone, and eremanthin which posses a common structural unit in A ring have been synthesized from 1-oxoeudesm-2-eno-13,6α-lactone in 7 steps. The key step involves solvolytic rearrangement of 1β-mesyloxyeudesm-4(14)-eno-13,6α-lactone.

Asking the 5 W's for designing next‐generation bioprocessing

AIChE Journal, EarlyView.
Abstract Biotechnology is expanding beyond traditional, centralized fermentation and toward next‐generation bioprocessing paradigms that emphasize flexible deployment outside the laboratory with application‐specific performance. However, many bioprocesses fail to translate beyond proof‐of‐concept into industrially viable systems because early design ...

Antinomic natural self-protection mechanism in long-lasting woods: a case study with three tropical species from French Guiana [PDF]

, 2009
We demonstrate in this work through 3 examples that Amazonian trees may specialize longlasting woods by means of at least to different approaches. Wallaba impregnates its wood with large amounts of weakly antifungal compounds acting in synergy, while ...

Quorum-quenching activity of the AHL-lactonase from Bacillus licheniformis DAHB1 inhibits vibrio biofilm formation in vitro and reduces shrimp intestinal colonisation and mortality [PDF]

, 2014
Vibrio parahaemolyticus is a significant cause of gastroenteritis resulting from the consumption of undercooked sea foods and often cause significant infections in shrimp aquaculture. Vibrio virulence is associated with biofilm formation and is regulated

Female‐Specific Risk of TAS2R Variants in Chronic Rhinosinusitis: A Hospital‐Based Cohort Study From the Taiwan Precision Medicine Initiative

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Bitter taste receptors (T2Rs) function in the innate immune defense of the sinonasal mucosa; however, the genetic association between the TAS2R gene family and chronic rhinosinusitis (CRS) remains understudied in Asian populations.

Ring Expansion Of Alkylidenecarbenes Derived From Lactams, Lactones, And Thiolactones Into Strained Heterocyclic Alkynes: A Theoretical Study [PDF]

, 2019
Strained cycloalkynes are of considerable interest to theoreticians and experimentalists, and possess much synthetic value as well. Herein, a series of cyclic alkylidenecarbenes—formally obtained by replacing the carbonyl oxygen of four-, five-, and six ...
