-
Paragraph 0101-0107, (2020/09/09)
The invention provides a novel phenolic compound and a preparation method and application thereof. The chemical general formula of the novel phenolic compound is as shown in formula (1), and R is Br,Cl or F. According to the novel phenolic compound, the growth of gram-positive bacteria can be obviously inhibited, the minimum inhibitory concentration on staphylococcus aureus, bacillus and methicillin-resistant staphylococcus aureus is 1-4mu g/mL, the drug resistance is not generated under long-time low-dose exposure, and the compound can be used as a gram-positive bacteria antibacterial agentand has a good antibacterial effect.

The replacement of a carboxylic acid with a surrogate structure, or (bio)-isostere, is a classical strategy in medicinal chemistry. The general underlying principle is that by maintaining the features of the carboxylic acid critical for biological activity, but appropriately modifying the physicochemical properties, improved analogs may result. In this context, a systematic assessment of the physicochemical properties of carboxylic acid isosteres would be desirable to enable more informed decisions of potential replacements to be used for analog design. Herein we report the structure-property relationships (SPR) of 35 phenylpropionic acid derivatives, in which the carboxylic acid moiety is replaced with a series of known isosteres. The data set generated provides an assessment of the relative impact on the physicochemical properties that these replacements may have compared to the carboxylic acid analog. As such, this study presents a framework for how to rationally apply isosteric replacements of the carboxylic acid functional group.

A broadly based investigation of the effects of a diverse array of substituents on the photochemical rearrangement of p-hydroxyphenacyl esters has demonstrated that common substituents such as F, MeO, CN, CO2R, CONH2, and CH3 have little effect on the rate and quantum efficiencies for the photo-Favorskii rearrangement and the release of the acid leaving group or on the lifetimes of the reactive triplet state. A decrease in the quantum yields across all substituents was observed for the release and rearrangement when the photolyses were carried out in buffered aqueous media at pHs that exceeded the ground-state pKa of the chromophore where the conjugate base is the predominant form. Otherwise, substituents have only a very modest effect on the photoreaction of these robust chromophores.

, (2008/06/13)
Certain novel fluorophenoxy compounds, principally aryloxyfluorophenoxyalkanoic acids and derivatives thereof, are described. More specifically, these novel compounds bear 1 to 4 fluorine substituents on the phenyl ring. These novel compounds exhibit surprising preemergent and postemergent activity when used according to the method of the invention in the control of grassy weeds.
