Synthesis, characterization and in-vitro evaluation of novel naphthoquinone derivatives and related imines: Identification of new anticancer leads

Quinones such as 1,4-naphthoquinones are abundant in nature and naphthoquinone based natural products are known to possess anticancer activity. This pharmacophore is known to convey anticancer activity to some drugs such as streptonigrin, mitomycin A, etc. We synthesized and characterized different classes of naphthoquinone derivatives including bis naphthoquinone, 2-arylaminonaphthoquinone, benzoxantene-6,11-dione and benzoacridine-5,6-dione derivatives instead of the expected 2-hydroxy-3-(substituted phenyl(aryl amino) methyl)naphthalene-1,4-dione derivatives from the reaction of 2-hydroxy1,4-naphthoquinone (lawson) with different benzaldehydes and aryl amines. Benzoacridine-5,6-dione derivatives and related imines showed potent anti-breast cancer activity in MCF-7 cancer cells. The in-vitro results revealed that five compounds benzoacridinedione derivatives (6b and 7b) and imines (13, 14 and 15) by the IC50 range of 5.4-47.99 muM are the most potent anti-breast cancer structures.

Asymmetric Petasis Borono-Mannich Allylation Reactions Catalyzed by Chiral Biphenols

Chiral biphenols catalyze the asymmetric Petasis borono-Mannich allylation of aldehydes and amines through the use of a bench-stable allyldioxaborolane. The reaction proceeds via a two-step, one-pot process and requires 2?8 mole % of 3,3?-Ph2-BINOL as the optimal catalyst. Under microwave heating the reaction affords chiral homoallylic amines in excellent yields (up to 99 %) and high enantioselectivies (er up to 99:1). The catalytic reaction is a true multicomponent condensation reaction whereas both the aldehyde and the amine can possess a wide range of structural and electronic properties. Use of crotyldioxaborolane in the reaction results in stereodivergent products with anti- and syn-diastereomers both in good diastereoselectivities and enantioselectivities from the corresponding E- and Z-borolane stereoisomers.

Flexible Entry into 3-Arylpent-2-enedioic Acids via Heck-Matsuda Arylation of Dimethyl Glutaconate with Arenediazonium Tosylates

For the preparation of compound libraries of Michael acceptors with tunable reactivity toward nuclophilic selenocysteine residue of thioredoxin reductase, a range of 3-arylglutaconic acids were required. The existing methods at the time had limited scope or involved several steps. A hitherto undescribed protocol for direct palladium(II) acetate-catalyzed arylation of glutaconic acid dimethyl ester at position 3 has been developed with a diverse set of arenediazonium tosylates followed by hydrolysis. This generally good-yielding two-step sequence displayed a propensity to deliver E -configured coupling products while compounds mostly featured in the literature were predominantly Z -configured. The possibility for preparing a library of 4-arylpyridine-2,6(1 H,3 H)-diones has been exemplified.

Diverse reactivity in microwave-promoted catalyst-free coupling of substituted anilines with ethyl trifluoropyruvate and biological evaluation

Diverse reactivity by coupling of substituted anilines with ethyl trifluoropyruvate was developed under microwave irradiation without catalysts to generate 3-trifluoromethyl-3-hydroxy oxindoles, aromatic hydroxy trifluoromethyl esters, and 1,2-dicarbonyl compounds in a fast and efficient manner. The plausible mechanism for obtaining different products was proposed. Furthermore, the anti-HIV activity of aromatic hydroxy trifluoromethyl esters was first reported. The best inhibitory activity against wild-type HIV-1 IIIB was exemplified by trifluoromethyloxindole 3q with an IC50 = 5.8 muM, which also displayed potential activity against Y181C mutant virus with an IC50 = 7.5 muM. More significantly, the activities of oxindoles 3q and 3r to inhibit K103N/Y181C double mutant HIV-1 reverse transcriptase (RT) are probably similar to that of the second-generation nonnucleoside inhibitor HBY 097 by docking calculation.

Exploring the Existing Drug Space for Novel pTyr Mimetic and SHP2 Inhibitors

Protein tyrosine phosphatases (PTPs) are potential therapeutic targets for many diseases. Unfortunately, despite considerable drug discovery efforts devoted to PTPs, obtaining selective and cell permeable PTP inhibitors remains highly challenging. We describe a strategy to explore the existing drug space for previously unknown PTP inhibitory activities. This led to the discovery of cefsulodin as an inhibitor of SHP2, an oncogenic phosphatase in the PTP family. Crystal structure analysis of SHP2 interaction with cefsulodin identified sulfophenyl acetic amide (SPAA) as a novel phosphotyrosine (pTyr) mimetic. A structure-guided and SPAA fragment-based focused library approach produced several potent and selective SHP2 inhibitors. Notably, these inhibitors blocked SHP2-mediated signaling events and proliferation in several cancer cell lines. Thus, SPAA may serve as a new platform for developing chemical probes for other PTPs.
