Purification, Fluorescent Labeling, and Detyrosination of Mammalian Cell Tubulin for Biochemical Assays

Cytoskeleton, EarlyView.
ABSTRACT Microtubules play essential roles in numerous cellular processes. All microtubules are built from the protein tubulin, yet individual microtubules can differ spatially and temporally due to their tubulin isotype composition and post‐translational modifications (PTMs).

A Short Total Synthesis of the Daucane Sesquiterpenoid Ferutinin

European Journal of Organic Chemistry, EarlyView.
Only nine steps were required to access the bioactive daucane sesquiterpene ester ferutinin (1) from 3‐methyl‐2‐cyclopentenone (3) and allyl p‐tolyl sulfoxide. A one‐pot 1,4‐addition/aldol sequence was used to rapidly provide diene 2 (TBS = tert‐butyldimethylsilyl), ring‐closing metathesis of which followed by alkylation and acylation gave rise to the ...

Enantiospecific Acid‐Catalysed Hydroperoxidation of Scalemic Tertiary Benzylic Alcohols Facilitating a Concise Asymmetric Synthesis of Yingzhaosu C

European Journal of Organic Chemistry, EarlyView.
Asymmetric synthesis of antimalarial yingzhaosu C was achieved in 4–5 steps by asymmetric Grignard synthesis of (R)‐gossonorol followed by novel enantiospecific hydroperoxidation. We report a concise asymmetric synthesis of antimalarial yingzhaosu C in 59% ee.

Effect of Pretreatment Methods on the Proximate Composition, Antinutritional Factors, Antioxidants Properties, and In Vitro Antidiabetic Activities of Hypsizygus ulmarius

Food Chemistry International, EarlyView.
The effect of pretreatment methods on the proximate content, antinutrient factors, antioxidant, and in vitro antidiabetic activities of elm oyster mushroom was studied. It was observed and statistically concluded that soaking in 0.5% salt solution for 5 min had the least deteriorating effect on the antioxidant and in vitro antidiabetic activities ...
