A method for treating an angiogenesis-related disorder. The method includes administrating to a subject in need thereof an effective amount of a compound of the formula: Each of Ar<；SUB>；1<；/SUB>；, Ar<；SUB>；2<；/SUB>；, and Ar<；SUB>；3<；/SUB>；, independently, is phenyl, thienyl, furyl, pyrrolyl, pyridinyl, or pyrimidinyl； each of R<；SUB>；1<；/SUB>；, R<；SUB>；2<；/SUB>；, R<；SUB>；3<；/SUB>；, R<；SUB>；4<；/SUB>；, R<；SUB>；5<；/SUB>；, and R<；SUB>；6<；/SUB>；, independently, is R, nitro, halogen, C(O)OR, C(O)SR, C(O)NRR', (CH<；SUB>；2<；/SUB>；)<；SUB>；m<；/SUB>；OR, (CH<；SUB>；2<；/SUB>；)<；SUB>；m<；/SUB>；SR, (CH<；SUB>；2<；/SUB>；)<；SUB>；m<；/SUB>；NRR', (CH<；SUB>；2<；/SUB>；)<；SUB>；m<；/SUB>；CN, (CH<；SUB>；2<；/SUB>；)<；SUB>；m<；/SUB>；C(O)OR, (CH<；SUB>；2<；/SUB>；)<；SUB>；m<；/SUB>；CHO, (CH<；SUB>；2<；/SUB>；)<；SUB>；m<；/SUB>；CH-NOR, or R<；SUB>；1 <；/SUB>；and R<；SUB>；2 <；/SUB>；together, R<；SUB>；3 <；/SUB>；and R<；SUB>；4 <；/SUB>；together, or R<；SUB>；5 <；/SUB>；and R<；SUB>；6 <；/SUB>；together are O(CH<；SUB>；2<；/SUB>；)<；SUB>；m<；/SUB>；O, in which each of R and R', independently, is H or C<；SUB>；1<；/SUB>；~C<；SUB>；6 <；/SUB>；alkyl； and m is 0, 1, 2, 3, 4, 5, or 6, and n is 0, 1, 2, or 3.
