Structure-activity relationships of estrogen derivatives as aromatase inhibitors. Effects of heterocyclic substituents

Aromatase, which is responsible for the conversion of androgens to estrogens, is a potential therapeutic target for the selective lowering estrogen level in patients with estrogen-dependent breast cancer. We prepared and tested series of the pyridine- and other heterocyclic ring-containing derivatives of 2- and 4-aminoestrones, estrone, and estradiol, compounds 5, 10, 12 and 15. The isonicotinyl derivatives of 2- and 4-aminoestrone, compounds 5c and 10c, were fairly potent competitive inhibitors of aromatase (KI, 2.1±0.14 and 1.53±0.08 mum for 5c and 10c, respectively) and other compounds did not show, to a significant extent, the aromatase inhibitory activity. This result suggests that the isonicotinyl-substituted derivatives 5c and 10c would be accessible to the active site of aromatase.

Discovery of 4-((N-(2-(dimethylamino)ethyl)acrylamido)methyl)-N-(4-methyl-3-((4-(pyridin-3-yl)pyrimidin-2-yl)amino)phenyl)benzamide (CHMFL-PDGFR-159) as a highly selective type II PDGFRalpha kinase inhibitor for PDGFRalpha driving chronic eosinophilic leukemia

Through exploration of the non-highly conserved allosteric hydrophobic pocket generated by DFG-out shifting in the inactive conformation, we discovered a highly selective type II PDGFRalpha kinase inhibitor 15i (CHMFL-PDGFRalpha-159), which exhibited strong potency against purified PDGFRalpha (IC50: 132 nM) but not structurally similar PDGFRbeta, ABL, c-KIT and VEGFR2 kinases. In addition, it displayed a high selectivity profile (S score (10) = 0.02) at the concentration of 1 muM among 468 kinases/mutants in the KINOMEscan profiling. X-ray crystal structure of 15i in complex with PDGFRalpha revealed a distinct binding feature in the allosteric hydrophobic pocket which might help to expand the diversity of type II kinase inhibitors. Compound 15i potently inhibited the proliferation of PDGFRalpha driving Chronic Eosinophilic Leukemia (CEL) cell line EOL-1 through strong blockage of PDGFRalpha mediated signaling pathways, arresting cell cycle progression, and induction of apoptosis. Furthermore, compound 15i effectively suppressed the EOL-1 tumor progression in the xenograft model and increased the survival rate in the engraftment tumor model.

Efficient solid-phase synthesis of 2,3-substituted indoles

The development of the solid-phase version of the modified Madelung indole synthesis is reported. The chemistry was initiated with the reductive amination of Bal resin using an ortho substituted aniline. The resin bound aniline was acylated with a variety of acid chlorides followed by cyclization with base to provide the desired indole after TFA-promoted cleavage from the resin.

Structure-activity relationships of substituted 1-pyridyl-2-phenyl-1,2- ethanediones: Potent, selective carboxylesterase inhibitors

Inhibition of intestinal carboxylesterases may allow modification of the pharmacokinetics/pharmacodynamic profile of existing drugs by altering half-life or toxicity. Since previously identified diarylethane-1,2-dione inhibitors are decidedly hydrophobic, a modified dione scaffold was designed and elaborated into a >300 member library, which was subsequently screened to establish the SAR for esterase inhibition. This allowed the identification of single digit nanomolar hiCE inhibitors that showed improvement in selectivity and measured solubility.

Vilsmeier reagent initialed sequential one-pot multicomponent synthesis of N,O-disubstituted glycolamides as dipeptidyl peptidase 4 inhibitors

A series of N,O-disubstituted glycolamide derivatives have been successfully synthesized through Vilsmeier reagent initialed sequential one-pot multicomponent procedure from alpha-chloro N-arylacetamides with formamide/PBr3 and acid chloride. The three-step synthesis involved Vilsmeier formyloxylation reaction, decarbonylation, and esterification. The strategy was also applicable to alpha-chloro N-(naphthalenyl)acetamide to prepare the corresponding N,O-disubstituted glycolamide products. All of N,O-disubstituted glycolamides were evaluated against dipeptidyl peptidase 4 inhibitory activity. Based on the inhibitory results, several of O-furan-2-carbonyl and O-quinoline-8-sulfonyl N-aryl glycolamide compounds possessed the better effective inhibition of dipeptidyl peptidase 4.

Diversity oriented synthesis of a vinblastine-templated library of 7-aryl-octahydroazonino[5,4-b]indoles via a three-component reaction

A vinblastine-templated library of 7-aryl-octahydroazonino[5,4-b]indoles was prepared by a three-component reaction from indolizino[8,7-b]indoles, chloroformates, and activated arenes via a chloroformate mediated fragmentation of the indolizinoindole nucleus followed by insertion of an activated arene. In addition to N3-carbamoyl-7-aryl-octahydroazonino[5,4-b]indoles prepared in one step, a wide range of N3-substituted substrates were synthesized in one pot via the derivatization of a versatile N3-H-azonino[5,4-b]indole intermediate generated in situ by application of the same strategy. A subset of 308 compounds out of a virtual library of 3216, representing 13 different chemotypes, was prepared by high throughput solution-phase synthesis and subsequently purified by mass-triggered high performance liquid chromatography (HPLC). A total of 188 compounds with a minimum purity of 80% by UV214 nm and 85% by evaporative light scattering detection (ELSD) was isolated for primary screening.
