Discovery of N-phenyl-(2,4-dihydroxypyrimidine-5-sulfonamido) phenylurea-based thymidylate synthase (TS) inhibitor as a novel multi-effects antitumor drugs with minimal toxicity

Cell Death and Disease, 2019
Thymidylate synthase (TS) is a hot target for tumor chemotherapy, and its inhibitors are an essential direction for anti-tumor drug research. To our knowledge, currently, there are no reported thymidylate synthase inhibitors that could inhibit cancer ...

Palladium-catalyzed synthesis of β-hydroxy compounds via a strained 6,4-palladacycle from directed C–H activation of anilines and C–O insertion of epoxides

Chemical Science, 2020
A palladium-catalyzed C–H activation of acetylated anilines (acetanilides, 1,1-dimethyl-3-phenylurea, 1-phenylpyrrolidin-2-one, and 1-(indolin-1-yl)ethan-1-one) with epoxides using O-coordinating directing groups was accomplished.

Efeitos da pulverização pré-colheita com thidiazuron sobre a qualidade e a maturação de frutos em macieiras [PDF]

, 2003
Apple trees, cultivars Gala and Fuji, were sprayed at full bloom with thidiazuron (TDZ) at the doses of 0, 5, 10, or 20 g (a.i.) ha-1 and fruit were assessed for quality and maturity. In both cultivars, the increase of TDZ dose had detrimental effects on

The implications of nitrogen on the fermentative growth extension of Saccharomyces cerevisiae by isoproturon [PDF]

, 2013
The peptone is used to provide nitrogen to Saccharomyces cerevisiae, which is an essential element for growth. In nature and in industrial musts, essential nutrients for yeast growth are available in complex and variable flux. Some of these compounds are

[Mathematical prediction of indicators of toxicity and hygienic standardization of phenylurea compounds].

Gigiena i sanitariia, 1990
The relation between physical and chemical constants and toxicometric indicators has been used as the basis of mathematical simulation both of separate indices of toxicity and preliminary safety exposure levels of the compounds of phenylurea series, thus it becomes possible to apply the derived mathematical links for rapid hygienic norm-setting of new ...

Impact of CPPU and combined CPPU-thidiazuron treatments on fruit quality and volatile compounds in 'Jinling Xiangxin' grapes

Technology in Horticulture
(2-Chloro-4-pyridyl)-N′-phenylurea (CPPU) is a widely used plant growth regulator (PGR) in table grape production to promote seedlessness and increase berry size. However, the mechanisms by which PGRs influence aroma quality remain poorly understood.
