Synthetic Route of 31608-22-7. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 31608-22-7, Name is 2-(4-Bromobutoxy)tetrahydro-2H-pyran
TETRONIC AND THIOTETRONIC ACID DERIVATIVES AS PHOSPHOLIPASE A2 INHIBITORS
There are disclosed compounds of the formula: wherein X is ¿CH2R; R is and further when Y=S, R may also be ¿(CH2)eCH3; Y is ¿O¿or ¿S¿; R1 and R2 are each, independently, hydrogen or lower alkyl; R3 is indolyl, furyl, phenyl or phenyl optionally mono- or disubstituted independently by alkyl of 1-7 carbon atoms, ¿C(CH3)3, ¿C(CH3)2CH2C(CH3), ¿C(CH3)2CH2CH3, haloloweralkyl, perfluoroalkyl, lower alkoxy, aryl alkoxy, halo or nitro; R4 and R5 are, independently, ¿COCH2R7, ¿CO2R7, ¿CONHR7, geranyl or CH2R3; R6 is hydrogen or lower alkyl; R7 is geranyl and any moiety selected from R other than AR5 A and B are, independently, ¿O¿, ¿S¿ or ¿NR6 ¿; and a is 0-8; b is 1-10 when Y=S, and 2-10 when Y=0; c is 1-3; d is 0-9; and e is 3-18; which by virtue of their ability to inhibit PLA2, are ofuse as antiinflammatory agents and there is also disclosed a method for the treatment of immunoinflammatory conditions, such as allergy, anaphylaxis, asthma and inflammation in mammals
