Development of potent small molecule inhibitors of protein-protein interactions with optimized druglike properties represents a challenging task in lead optimization process. Here, we report synthesis and structure-based optimization of new thienopyrimidine class of compounds, which block the protein-protein interaction between menin and MLL fusion proteins that plays an important role in acute leukemias with MLL translocations. We performed simultaneous optimization of both activity and druglike properties through systematic exploration of substituents introduced to the indole ring of lead compound 1 (MI-136) to identify compounds suitable for in vivo studies in mice. This work resulted in the identification of compound 27 (MI-538), which showed significantly increased activity, selectivity, polarity, and pharmacokinetic profile over 1 and demonstrated a pronounced effect in a mouse model of MLL leukemia. This study, which reports detailed structure-activity and structure-property relationships for the menin-MLL inhibitors, demonstrates challenges in optimizing inhibitors of protein-protein interactions for potential therapeutic applications.

, p. 2756 - 2762 (2013/08/23)
A simple and convenient procedure for the synthesis of nitriles by dehydration of aldoximes using a PCC (pyridiniumchlorochromate) has been developed. A variety of aromatic, heteroaromatic, and aliphatic aldoximes are converted. Supplementary materials are available for this article.

Antifolates for the treatment of cardiovascular, inflammatory, neoplastic, autoimmune and related diseases in sublingual dosage units, film strips, or skin patches

Page/Page column 4, (2010/11/03)
New metabolism blocked antifolates and their salts are provided along with new indications (coronary heart disease, cardiovascular diseases, stroke and termination of tubal or ectopic pregnancy) and methods (sublingual dosage forms, filmstrips or patches) for their use and delivery. Sublingual dosage forms or trans-dermal patches of metabolically blocked entities of this invention offer superior alternatives to traditional oral dosage forms to achieve greater and predictable therapeutic efficacy, lower toxicity and to overcome drug resistance by virtue of elimination of oxidative deactivation and production of toxic metabolites. Metabolism blocked antifolates bearing a fluorinated benzene ring, a thiophene ring, a pyrrole ring, a furan ring or a 8-deazapteridine ring that are provided in this invention are not previously described. The use of metabolism blocked antifolates to terminate medically complicated pregnancies that are taught herein are new inventions targeted to eliminate drug related toxicity to the host and to enhance therapeutic efficacy.

Page 4, (2010/02/06)
This invention relates to a process for synthesizing certain folic acid analogues, which are useful in treating cancer, inflammatory diseases, autoimmune diseases, and are commonly referred to as antifolates. The process employs improved steps for annulation, derivatization and addition reactions to produce the described antifolates from commonly available starting materials.
Nitration of moderately deactivated arenes with nitrogen dioxide and molecular oxygen under neutral conditions. Zeolite-induced enhancement of regioselectivity and reversal of isomer ratios
Peng, Xinhua,Fukui, Naoyuki,Mizuta, Masayuki,Suzuki, Hitomi
, p. 2326 - 2335 (2007/10/03)
In the presence of zeolites, moderately deactivated arenes such as 1-nitronaphthalene, naphthonitriles, and methylated benzonitriles can be smoothly nitrated at room temperature by the combined action of nitrogen dioxide and molecular oxygen. The regioselectivity is considerably improved as compared with the conventional nitration methodology based on nitric and sulfuric acids. In some cases, the minor isomer became favoured to a significant extent, resulting in the reversal of ordinary isomer ratios of nitration products.

A classical folate analog inhibitor of dihydrofolate reductase incapable of both polyglutamylation and aldehyde oxidase mediated 7-hydroxylation is described. The title compound 4'-methylene-5,8,10-trideazaaminopterin [Mobiletrex; M-Trex] exhibited excellent inhibition of human dihydrofolate reductase and the growth of a number of human tumor cells in culture. Unlike methotrexate, mobiletrex was not a substrate of either folylpolyglutamate synthetase or rabbit liver aldehyde oxidase. Mobiletrex caused total growth inhibition (TGI) of a number of human tumor cells at therapeutically relevant concentrations (~ 1x10 -6 M) which are potencies strikingly higher than those of methotrexate.

Addition of tetraethylammonium cyanide to a solution of η5-cyclopentadienyl)(η6-arene)iron (1 +), in acetonitrile can be studied by voltammetry.With electron-withdrawing groups such as nitro, keto, sulfone, azo and azoxy bonded to the arene, the reaction occurs immediately and a wave resulting form oxidation of hexadienyl species is observed in the range 0-IV vs.SCE.Preparation of various hexadienyl compounds was achieved with good yields.In order to obtain ortho-substituted benzonitriles, electrochemical and chemical oxidations of hexadienyl complexes were compared.The best results were obtained with N-bromosuccinimide (NBS) and a demetallation generally occurs.A one-pot synthesis of benzonitrile compounds can be achieved after addition of cyanide ion and then NBS to a solution of (η5-cyclopentadienyl)(η6-arene) iron (1 +) in acetonitrile. 6-C6H5N(O)=NC6H4Cn-2>>+ is directly obtained from the azoxy dicationic compound 2+.Keywords: Iron; Ferrocenes; Electrochemistry; Arene complexes; Oxidation
3H-azepines and related systems. Part 5. Photo-induced ring expansions of o-azidobenzonitriles to 3-cyano- and 7-cyano-3H-azepin-2(1H)-ones
Lamara,Redhouse,Smalley,Thompson
, p. 5515 - 5525 (2007/10/02)
Unlike other aryl azides bearing electron-withdrawing ortho-substituents, o-azidobenzonitriles on photolysis in aqueous-tetrahydrofuran yield mixtures of the expected 3-cyano- and the unexpected 7-cyano-3H-azepin-2(1H)-ones. In one instance ring contraction to a 2-azabicyclo[3.2.0]hept-6-ene-3-one is noted. X-ray crystallographic data for 7-cyano- and 4-chloro-7-cyano-3H-azepin-2-one, and for the azabicycloheptenone, are presented.
