Characterization of Amphiphilic Polymers

1H, 13C, 29Si and 31P NMR spectra were recorded using either a JEOL Eclipse 300 MHz, JEOL Eclipse 400 MHz, Varian VNMR 400 MHz or Varian VNMR 500 MHz spectrometer. The chemical shifts (δ) are reported in parts per million (p.p.m.) and the coupling constants (J) in Hertz (Hz). Chemical shifts were referenced to residual dichloromethane at δ 5.32 p.p.m. (1H), and benzene at δ 7.14 p.p.m. (1H) and δ 128.06 p.p.m. (13C). 1H NMR integrations for the polymers were calculated after setting the methyl protons (6H) of PFS to 378H for PFS63-b-PDMS513, 408H for PFS68-b-PMVS670 and 360H for PFS60-b-PMVS574.

Synthesis of Dihydrofuranaphthoquinones for Antifungal Screening

Check if the same lab product or an alternative is used in the 5 most similar protocols
All the dihydrofuranaphthoquinones used for antifungal screening against S. brasiliensis and S. schenckii were prepared from lawsone by different methods (Scheme 1) with a yield of 23–76%. The α- and β-2,3-dihydrofuranaphthoquinones 5–18 were prepared as previously described in the literature [35 (link),48 (link)] and were confirmed by 1H-NMR spectra recorded on a Varian VNMR (500 MHz) spectrometer using chloroform-d as a solvent and tetramethylsilane as an internal standard. The α- and β-2,3-dihydrofuranaphthoquinones 19–21 were prepared from nor-lapachol, as previously described [49 (link),50 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
