This invention relates to methods for screening compounds for antitubulin activity, evaluation of cells for sensitivity to antitubulin drugs, resistance monitoring and quantifying tubulin using certain amides that inhibit the growth of eukaryotic cells as probes in binding assays, said amides having the structural formula
wherein
A is cycloalkyl, alkyl, haloalkyl, alkylthio, haloalkylthio, alkenyl, haloalkenyl, alkynyl, haloalkynyl, alkoxy, haloalkoxy, or phenyl, pyridyl, furyl, thienyl, isoxazolyl, oxazolyl, pyrrolyl, isothiazolyl, thiazolyl, pyrazolyl, imidazolyl, pyrimidinyl, quinolyl, isoquinolyl, naphthyl, pyridazinyl, pyrazinyl, benzothienyl, indolyl, benzofuranyl or benzyl, all optionally substituted in an acceptable manner with up to 4 substituents;
R1 and R2 are each independently a hydrogen atom, alkyl, haloalkyl, alkenyl, haloalkenyl, alkynyl or haloalkynyl, provided that both R1 and R2 are not a hydrogen atom; and
X, Y and Z are each independently a hydrogen atom, halo, cyano, thiocyano, isothiocyano or alkylsulfonyloxy, provided that at least one of X, Y and Z is not a hydrogen atom; or
the optical enantiomers thereof.
该发明涉及一种筛选具有抗微管活性的化合物的方法,评估细胞对抗微管药物的敏感性,抗微管药物的耐药监测以及利用抑制真核细胞生长的某些酰胺作为探针在结合测定中定量微管。所述酰胺具有结构式,其中A为环烷基、烷基、卤代烷基、烷硫基、卤代烷硫基、烯基、卤代烯基、炔基、卤代炔基、烷氧基、卤代烷氧基、苯基、吡啶基、呋喃基、噻吩基、异噁唑基、噁唑基、吡咯基、异噻唑基、噻唑基、吡唑基、咪唑基、喹啉基、异喹啉基、萘基、吡啶啉基、吡嗪基、苯并噻吩基、吲哚基、苯并呋喃基或苄基,其中所有基团可选择以最多4个取代基合适地取代;R1和R2分别独立地为氢原子、烷基、卤代烷基、烯基、卤代烯基、炔基或卤代炔基,但要求R1和R2不同时为氢原子;X、Y和Z分别独立地为氢原子、卤素、氰基、硫氰基、异硫氰基或烷基磺酰氧基,但要求X、Y和Z中至少有一个不是氢原子;或其光学对映体。
