Paragraph 0274; 0275, (2018/05/03)
An objective of the present invention is to provide low-molecular-weight compounds that can inhibit Src family kinases. The present invention relates to compounds represented by general formula (I) or pharmacologically acceptable salts thereof. In the formula, Ar1 is optionally substituted C6-10 arylene or 5- to 10-membered heteroarylene, and Ar2 is optionally substituted C6-10 aryl or 5- to 10-membered heteroaryl. R1 and R2 are defined as described in the specification.
Synthesis of symmetric dinitro-functionalised troeger's base analogues

supporting information; experimental part, p. 687 - 698 (2009/07/17)
The synthesis of six new examples of 2,8-dinitro-substituted Troeger's base analogues are reported, together with the first examples of 1,7-, 3,9- and 4,10-dinitro Troeger's base analogues and the first example of a tetranitro Troeger's base compound. Several of these dinitro compounds lack substituents at the 2- and 8-positions and therefore provide further examples of Troeger's base analogues derived from anilines lacking a para substituent.

Isomeric benzothiazoles having the nitro and methyl groups ortho to each other are converted into tautomeric aci-nitro derivatives on irradiation in heptane solution; in water, the corresponding more deeply colored anions are formed. The efficiency of pho
RADICAL-ANIONS OF AROMATIC COMPOUNDS. XVI. ELECTRONIC STRUCTURE OF RADICAL-ANIONS AND THE DIRECTION OF PARTIAL REDUCTION OF DISUBSTITUTED DERIVATIVES OF m-DINITROBENZENE: THE RELATIVE EFFECTS OF THE SUBSTITUENTS

It was shown by means of compounds labeled with the 15N isotope that the radical-anions of a wide range of 1,5-disubstituted 2,4-dinitrobenzenes are in most cases characterized by localization of the density of the unpaired electron at one of the nitro groups.It was concluded that the substituents can be arranged in the following order according to their ability to stabilize the form with the negatively charged nitro group at the para position: CO2- > CH3 Br > Cl N(C2H5)2 > CN > OCH3; CO2- > I.The relative effectiveness of the substituents which stabilize the form of the radical-anions with the negatively charged nitro group at the ortho position was determined theoretically as follows: OCH3 +C5H5 +H(C2H5)2.The position of the substituents in the series given above are determined by the combined effect of such factors as the effective volume, the electronic effect transmitted through the skeleton, the field effect, and the ability to form intramolecular hydrogen bonds.It was shown that the direction of partial reduction of the derivatives of m-dinitrobenzene can be predicted on the basis of data on the electronic structure of their radical-anions, which are probable key intermediates of the processes.
