Discovery of a potent dual EGFR/HER-2 inhibitor L-2 (selatinib) for the treatment of cancer
摘要:
To develop potent dual EGFR/HER-2 inhibitors with improved druggability, a series of new lapatinib analogs were designed and synthesized. Compared with lapatinib, L-2, L-4 and M-6 were more active against BT-474 or NCI-N87 cells. In vivo efficacy studies indicated that L-2 significantly suppressed tumor growth in NCI-N87 (94.8% inhibition) or SK-OV-3 xenograft (85.7% inhibition) without causing significant loss of body weight. And the inhibition rates of lapatinib in the two xenograft models were 89.7% and 78.8%, respectively. Moreover, further studies revealed that the potent in vivo activities of L-2 may be mainly attributed to its superior aqueous solubility and oral bioavailability. In addition, a high-yielding one-pot procedure was developed for the synthesis of lapatinib and its analogs. (C) 2013 Elsevier Masson SAS. All tights reserved.

[EN] A NOVEL PROCESS FOR THE PREPARATION OF LAPATINIB AND ITS PHARMACEUTICALLY ACCEPTABLE SALTS [FR] NOUVEAU PROCÉDÉ DE PRÉPARATION DE LAPATINIB ET DE SES SELS DE QUALITÉ PHARMACEUTIQUE
The present application provides novel substituted quinazoline and pyrido-pyrimidine compounds and pharmaceutically acceptable salts, prodrugs, and solvates thereof. Also provided are methods for preparing these compounds. These compounds are useful in co-regulating PI3K and/or mTOR activity by administering a therapeutically effective amount of one or more of the compounds to a patient. By doing so, these compounds are effective in treating conditions associated with the dysregulation of the PI3K/AKT/mTOR pathway. Advantageously, these compounds perform as dual PI3K/mTOR inhibitors. A variety of conditions can be treated using these compounds and include diseases which are characterized by inflammation or abnormal cellular proliferation. In one embodiment, the disease is cancer.

active and efficient catalyst system derived from a palladium precatalyst and monophosphine ligands 1 or 2 for the Suzuki-Miyaura cross-coupling reaction of heteroaryl boronic acids and esters has been developed. This method allows for the preparation of a wide variety of heterobiaryls in good to excellent yields and displays a high level of activity for the coupling of heteroaryl chlorides as well as

Suzuki–Miyauracoupling of heteroaryls is an important method for the preparation of compound libraries for medicinal chemistry and materials research. Although many catalysts have been developed, none of them have been generally applicable to the coupling reactions of heteroarylchlorides and tosylates at room temperature. We discovered that a catalyst combination of Pd(OAc)2 and XPhos (2-dicyclohexylphosphanyl-2′

The present invention relates to a method for identifying compounds that modulate the activity of p300/CBP. Compounds of the invention are identified by designing or screening for a compound which binds to at least one amino acid residue of the newly identified lysine-CoA inhibitor binding site, L1 loop, electronegative pocket, or electronegative groove of the HAT domain of p300/CBP and testing the compound for its ability to modulate the activity of p300/CBP. Compositions and methods for preventing or treating diseases or disorders associated with p300/CBP are also provided as is a method for producing a semi-synthetic HAT domain.
