Regioselective synthesis of angular nitrogen polyheterocycles: dipyrido[3,2-a:2′,3′-c]quinolino[2,3-h]phenazines
摘要:
Novel polyaza heterocycles, dipyrido[3,2-a:2',3'-c]quinolino[2,3-h]phenazines, were synthesized via a regiocontrolled condensation between 5,6-phendione and 3,4-diaminoacridine derivatives. (C) 2002 Elsevier Science Ltd. All rights reserved.

The present invention provides simple, rapid methods and procedures for analyzing cells, hereunder quantitative and qualitative assessment of cells, such as viability. The present invention relates to the use of various optionally substituted reporter compounds particularly detectable upon their reaction with thiol-containing species present in higher concentrations in intact (e.g., living) cells than in non-intact (e.g., dead, stressed and apoptotic) cells. The present invention also relates to the use of various optionally substituted reporter compounds particularly detectable upon their reaction with species present in intact and/or non-intact cells. Moreover, the present invention relates to the use of measuring techniques and/or instruments coupled with the use of various optionally substituted reporter compounds. The invention further relates to compositions used in methods for analyzing cells, such as a composition comprising N-(7-dimethylamino-4-methyl-3-coumarinyl)-maleimide (DACM).
