Samuel Eyley et al.
Nanoscale, 7(34), 14413-14421 (2015-08-08)
Cellulose nanocrystals were grafted with imidazole functionalities up to DS 0.06 using a one-pot functionalization strategy. The resulting nanocrystals were shown to have a pH responsive surface charge which was found to be positive below pH 6 and negative above
Q Yu et al.
Chemical communications (Cambridge, England), 50(81), 12150-12153 (2014-09-02)
LiYF4:Tm(3+)/Yb(3+) upconverting nanoparticles (UCNPs) were functionalized with the second generation photosensitizer 5,10,15,20-tetra(m-hydroxyphenyl)chlorin (m-THPC, Temoporfin, Foscan®). m-THPC was modified using 4-(bromomethyl)benzoic acid, which induced a bathochromic shift of the m-THPC blue absorption peak. The nanoconstruct causes up to 70% cell death
Chendong Ji et al.
Chemistry, an Asian journal, 11(16), 2316-2321 (2016-07-14)
Electrospun ultrathin fiber-based sensors are desirable because of their practicality and sensitivity. Ammonia-detection systems are in high demand in different areas, including the industrial and agricultural fields. However, current technologies rely on large and complex instruments that restrict their actual
Yan Shi et al.
Cell chemical biology, 26(3), 319-330 (2019-01-22)
Long noncoding RNA (lncRNA) are regulatory RNAs >200 nt. We previously showed that lncRNA GAS5 decreases significantly in serum of type 2 diabetes mellitus (T2DM) patients. Hence, we sought to decipher the molecular mechanisms underlying the role of GAS5 in
Salvatore Lombardo et al.
Langmuir : the ACS journal of surfaces and colloids, 33(22), 5473-5481 (2017-05-13)
The interaction of bovine serum albumin (BSA) with sulfated, carboxylated, and pyridinium-grafted cellulose nanocrystals (CNCs) was studied as a function of the degree of substitution by determining the adsorption isotherm and by directly measuring the thermodynamics of interaction. The adsorption
Marcela S Lopes et al.
European journal of medicinal chemistry, 46(11), 5443-5447 (2011-09-24)
A series of nitroaromatic compounds was synthesized and evaluated as potential antileishmanial and trypanocidal agents. Five compounds exerted significant anti-leishmanial activity in vitro against promastigotes forms of Leishmania (L.) amazonensis, with IC(50) in the range of 23-59 μmol L(-1), but
Zhimei He et al.
Small (Weinheim an der Bergstrasse, Germany), 15(4), e1804131-e1804131 (2018-12-20)
During photodynamic therapy (PDT), severe hypoxia often occurs as an undesirable limitation of PDT owing to the O2 -consuming photodynamic process, compromising the effectiveness of PDT. To overcome this problem, several strategies aiming to improve tumor oxygenation are developed. Unlike
Dries Vandamme et al.
Bioresource technology, 194, 270-275 (2015-07-27)
This study presents a novel flocculant for harvesting Chlorella vulgaris as model species for freshwater microalgae based on cellulose nanocrystals (CNCs), thus synthesized from a renewable and biodegradable resource. Cationic pyridinium groups were grafted onto CNCs by two separate one-pot
Zhen Wu et al.
Chemistry, an Asian journal, 11(21), 3102-3106 (2016-09-21)
Spiropyran (SP), which can respond to acid, ultraviolet irradiation, and mechanical force, has received great attention as a classic molecule for the construction of stimuli-responsive materials. However, the self-assembly behavior of SP with a tunable morphology has rarely been investigated.
Rosanna Maccari et al.
Bioorganic & medicinal chemistry, 15(15), 5137-5149 (2007-06-05)
4-(5-Arylidene-2,4-dioxothiazolidin-3-yl)methylbenzoic acids (2) were synthesized and evaluated in vitro as inhibitors of PTP1B and LMW-PTP, two protein tyrosine phosphatases (PTPs) which act as negative regulators of the metabolic and mitotic signalling of insulin. The synthesis of compounds 2 represents an
