In exploring further the structural features that influence the relative efficacy of analogues of aminoglutethimide as inhibitors of the cholesterol side-chain cleavage enzyme system desmolase and the estrogen forming system aromatase, analogues have been synthesized in which the aminophenyl substituent is replaced by pyridyl or substituted pyridyl.The 4-pyridyl analogue 5 is a strong competitive inhibitor of aromatase (Ki-1.1 μM; value for 1, 0.60 μM), which exhibits a type II difference spectrum (Ks = 0.28 μM; value for 1, 0.13 μM) but is noninhibitory toward desmolase.The 2- and 3-pyridyl analogues (3 and 4) inhibit neither enzyme system. 1-Amino-3-ethyl-3-phenylpiperidine-2,6-dione (2) is a strong and selective inhibitor of desmolase but the 4-pyridyl analogue 10 is a weak inhibitor of desmolase and aromatase.Analogues of 5 having a less basic aromatic substituent, namely, the N-oxide 11 and the 2,3,5,6-tetrafluoro derivative 13, were also prepared.The latter is a weak inhibitor of aromatase and the former inhibits neither enzyme system

3-Alkyl- or fluoroalkyl-3-(4-pyridyl)piperidine-2,6-diones, useful in the treatment of breast cancer, of formula STR1 wherein R represents an alkyl group having 2 to 10 carbon atoms or a fluoroalkyl group having 2 to 5 carbon atoms and A is hydrogen or an alkyl group having 1 to 4 carbon atoms, are prepared by reacting a 4-pyridylacetate with an alkyl or fluoroalkyl iodide, chloride or bromide, in the presence of a sterically bulky base and reacting the product with acrylamide in the presence of a sodium or potassium branched chain alkoxide. Preferably potassium t-butoxide is used in both stages and they are carried out sequentially at room temperature in an alcoholic or polar, aprotic solvent in a single reaction vessel.

PCT No. PCT/GB84/00425 Sec. 371 Date Jul. 16, 1985 Sec. 102(e) Date Jul. 16, 1985 PCT Filed Dec. 10, 1984 PCT Pub. No. WO85/02618 PCT Pub. Date Jun. 20, 1985.In the treatment of estrogen-dependent tumors, it is desirable to improve the therapy obtainable from the compound aminoglutethimide. It has now been found that 3-ethyl-3-(4-pyridyl)glutarimide and derivatives thereof of formula wherein R represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms offers advantages over aminoglutethimide. 3-Ethyl-3-(4-pyridyl)glutarimide can be prepared by various ring-closing reactions, especially by heating 4-(4-pyridyl)-hexano-1,4-dinitrile with a strong mineral acid.

We describe a 'one-pot' synthesis of the aromatase inhibitor pyridoglutethimide and its 3-octyl-analogue, together with details of the resolution of the former using chiral stationary phase hplc.
Synthesis of the Aromatase Inhibitor 3-Ethyl-3-(4-pyridyl)piperidine-2,6-dione and Its Enantiomers

Convenient syntheses of (R/S)-3-ethyl-3-(4-pyridyl)piperidine-2,6-dione (pyridoglutethimide) and its enantiomers are described; aromatase inhibitory activity was almost entirely confined to the 3R-enantiomer

, (2008/06/13)
In the treatment of oestrogen-dependent tumors, it is desirable to improve the therapy obtainable from the compound aminoglutethimide. It has now been found that 3-ethyl-3-(4-pyridyl)glutarimide derivatives of formula STR1 wherein: (a) R1 represents an ethyl group and R2 represents a methyl group, an alkyl or cycloalkyl group having 3 to 10 carbon atoms, or a fluoroalkyl group having 2 to 10 carbon atoms; (b) R1 represents an alkyl group having 3 to 10 carbon atoms or a fluoroalkyl group having 2 to 5 carbon atoms and R2 represents a hydrogen atom; or, (c) R1 represents an alkyl group having 3 to 8 carbon atoms or a fluoroalkyl group having 2 to 5 carbon atoms and R2 represents an alkyl or fluoroalkyl group having 2 to 8 carbon atoms, provided that the total number of carbon atoms in R1 and R2 is not more than 10; and therapeutically acceptable acid addition salts of the above compounds.
