DERIVATIVES OF 2-AMINO-4H-3,1-BENZOXAZINE-4-ONE FOR PROPHYLAXIS OR TREATMENT OF OBESITY OR ACCOMPANYING DISORDER

FIELD: organic chemistry, biochemistry, medicine. ^ SUBSTANCE: invention describes a method for prophylaxis or treatment of states wherein inhibition of enzyme activity is required wherein this enzyme catalyzes hydrolysis reaction of ester functional groups and wherein indicated disorder represents obesity or accompanying disease. Method involves prescribing compound of the formula (1): ^ or its pharmaceutically acceptable salt, ester, amide or precursor wherein in the formula (1) a means six-membered aromatic or heteroaromatic ring; R1 means a branched or unbranched alkyl (its carbon chain can be broken possibly by one or more oxygen atoms), alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, arylalkyl, reduced arylalkyl, arylalkenyl, heteroaryl, heteroarylalkyl, heteroarylalkenyl, reduced aryl, reduced heteroaryl, reduced heteroarylalkyl or their substituted derivative wherein a substitute represents one or more group taken independently among the following group: halogen atom, alkyl, halogen-substituted alkyl, aryl, arylalkyl, heteroaryl, reduced heteroaryl, reduced heteroarylalkyl, arylalkoxy-, cyano-, -C(O)R4, -CO2R4, -SOR4, -SO2R4, -NR6R7, -OR6, -SR6, -C(O)CX1X2NR6R7, -C(O)NR4R5, -C(O)N(OR5)R6, -NR6C(O)R4, -CR6(NH2)CO2R6, -NCX1X2CO2R6, -N(OH)C(O)NR6R7, -N(OH)C(O)R4, -NHC(O)NR6R7, -C(O)NHNR6R7, -C(O)N(OR5)R6, or lipid or steroid (natural or synthetic one) under condition that any substituting heteroatom in R1 or R2 must be segregated from nitrogen exocyclic atom by at least two carbon atoms (preferably, saturated ones); R2 means hydrogen atom or group, such as determined for R1 and wherein R4 represents hydrogen atom, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, reduced heteroaryl or reduced heteroarylalkyl, OR6, NHCX1X2CO2R6 or NR6R7; R5 represents hydrogen atom, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, reduced heteroaryl or reduced heteroarylalkyl; R6 and R7 are taken independently among hydrogen atom, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, arylalkyl, heteroaryl, reduced heteroaryl, heteroarylakyl, reduced heteroarylalkyl or -(CH2)n(OR5)m wherein n = from 1 to 12 but preferably from 2 to 10; m = from 1 to 3; for R5 (C2-C10)-alkyl is preferable; X1 and X2 represent independently hydrogen atom, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, arylalkyl, heteroaryl, reduced heteroaryl, heteroarylalkyl or reduced heteroaryl
