Dry double-sided tape for adhesion of wet tissues and devices.
Yuk H, Varela CE, Nabzdyk CS, Mao X, Padera RF, Roche ET, Zhao X. Yuk H, et al. Nature. 2019 Nov;575(7781):169-174. doi: 10.1038/s41586-019-1710-5. Epub 2019 Oct 30. Nature. 2019. PMID: 31666696
Here we propose an alternative tissue adhesive in the form of a dry double-sided tape (DST) made from a combination of a biopolymer (gelatin or chitosan) and crosslinked poly(acrylic acid) grafted with N-hydrosuccinimide ester. The adhesion mechanism of this DST relies on …

Flavour-active wine yeasts.
Cordente AG, Curtin CD, Varela C, Pretorius IS. Cordente AG, et al. Appl Microbiol Biotechnol. 2012 Nov;96(3):601-18. doi: 10.1007/s00253-012-4370-z. Epub 2012 Sep 1. Appl Microbiol Biotechnol. 2012. PMID: 22940803 Free PMC article. Review.
Where once the role of yeast in fermented beverage flavour was thought to be limited to a small number of volatile esters and higher alcohols, the discovery that wine yeast release highly potent sulfur compounds from non-volatile precursors found in grapes has driven resea …

Stereocontrolled Total Synthesis of (-)-Stemaphylline.
Varela A, Garve LK, Leonori D, Aggarwal VK. Varela A, et al. Angew Chem Int Ed Engl. 2017 Feb 13;56(8):2127-2131. doi: 10.1002/anie.201611273. Epub 2017 Jan 18. Angew Chem Int Ed Engl. 2017. PMID: 28097799 Free PMC article.
By performing a solvent switch from Et(2) O to CHCl(3) , efficient 1,2-metalate rearrangement of the intermediate boronate occurs with both halide and ester leaving groups. The methodology was used in the total synthesis of the Stemona alkaloid (-)-stemaphylline in just 11 …

Esterification of p-Coumaric Acid Improves the Control over Melanoma Cell Growth.
Carmo-Martins JI, Gonzatti MB, Varela MT, Sousa MEP, Costa LVS, Rodrigues EG, Fernandes JPS, Keller AC. Carmo-Martins JI, et al. Biomedicines. 2023 Jan 12;11(1):196. doi: 10.3390/biomedicines11010196. Biomedicines. 2023. PMID: 36672704 Free PMC article.
Because the esterification of p-coumaric acid (p-CA) enhanced its activity as an antimelanogenic agent, we aimed to determine the antitumor potential of two derivatives, the ethyl and butyl esters, against the murine B16-F10 and the human SK-MEL-25 melanoma cells. ...Altho …

Inhibition of Cysteine Proteases via Thiol-Michael Addition Explains the Anti-SARS-CoV-2 and Bioactive Properties of Arteannuin B.
Varela K, Arman HD, Berger MS, Sponsel VM, Lin CA, Yoshimoto FK. Varela K, et al. J Nat Prod. 2023 Jul 28;86(7):1654-1666. doi: 10.1021/acs.jnatprod.2c01146. Epub 2023 Jul 17. J Nat Prod. 2023. PMID: 37458412
This methyl ester was thought to be formed from the reaction between arteannuin B and the extracting solvent, which was supported by the fact that arteannuin B underwent 1,2-addition when it was dissolved in deuteromethanol. In contrast, in the presence of N-acetylcysteine …
