  • Patent number: 8802701
    Abstract: The present invention refers to new compounds represented by the general formula (I) where X is represented by the general formula (II) and Y is represented by the general formula (III). The relation X to Y may vary from 1:1 to 1:7. The radicals R1, R2, R3, R4, R5, and R6 in formula (II) are represented by: R1=H, CF3, CH3, OCH3, NH2, halogen; R2=H, CH3, NH2, halogen, NH—CHCH3(CH2)3N(C2H5)(CH2CH2OH), CH(OH)-2(C5H11N), NH—R7—N—(C2H5)2; R3=H, m-OC6H4CF3, NH2; R4=H, CH3, OCH3, NH2, halogen; R5=H, CH3, CF3, NH2, halogen; R6=H, CF3, CH3, NH2, halogen, NH—R8—N—(C2H5)2, NHCH(CH3)(CH2)3NH2; R7=(CH2)2, (CH2)3, CHCH3CH2, (CH2)4, (CH2)5, CHCH3(CH2)3, (CH2)6, (CH2)8, (CH2)10, (CH2)12; R8=CHCH3(CH2)3, CHCH3(CH2)CHCH3, (CH2)2, (CH2)3, (CH2)6, (CH2)3O(CH2)3. This invention also refers to a process of preparation of these compounds (formula I), and antiparasitic pharmaceutical compositions thereof.

  • Patent number: 8071777
    Abstract: The present invention refers to new compounds derived from artesunate salts with quinolines represented by the general formula (I) where X is represented by the general formula (II) and Y is represented by the general formula (III) depending on the radicals substituted in X (formula II), the relation X to Y (formula III) may vary from 1:1 to 1:7, because the amount of Y depends on the amount of N available in X for the formation of the salt. The radicals R1, R2, R3, R4, R5, e R6 in the general formula (II) are represented by: R1?H, CF3, CH3, OCH3, NH2, halogen; R2?H, CH3, NH2, halogen, NH—CHCH3(CH2)3N(C2H5)(CH2CH2OH), CH(OH)-2(C5H11N), NH—R7—N—(C2H5)2; R3?H, m-OC6H4CF3, NH2; R4?H, CH3, OCH3, NH2, halogen; R5?H, CH3, CF3, NH2, halogen; R6?H, CF3, CH3, NH2, halogen, NH—R8—N—(C2H5)2, NHCH(CH3)(CH2)3NH2; R7?(CH2)2, (CH2)3, CHCH3CH2, (CH2)4, (CH2)5, CHCH3(CH2)3(CH2)6, (CH2)8, (CH2)10, (CH2)12; R8?CHCH3(CH2)3, CHCH3(CH2)CHCH3, (CH2)2, (CH2)3, (CH2)6, (CH2)3O(CH2)3.
