Efficient Synthesis of Immunomodulatory Drug Analogues Enables Exploration of Structure?Degradation Relationships

The immunomodulatory drugs (IMiDs) thalidomide, pomalidomide, and lenalidomide have been approved for the treatment of multiple myeloma for many years. Recently, their use as E3 ligase recruiting elements for small-molecule-induced protein degradation has led to a resurgence in interest in IMiD synthesis and functionalization. Traditional IMiD synthesis follows a stepwise route with multiple purification steps. Herein we describe a novel one-pot synthesis without purification that provides rapid access to a multitude of IMiD analogues. Binding studies with the IMiD target protein cereblon (CRBN) reveals a narrow structure?activity relationship with only a few compounds showing sub-micromolar binding affinity in the range of pomalidomide and lenalidomide. However, anti-proliferative activity as well as Aiolos degradation could be identified for two IMiD analogues. This study provides useful insight into the structure?degradation relationships for molecules of this type as well as a rapid and robust method for IMiD synthesis.

Synthesis and study of the properties of thermoset oligoimides with propargyl fragment

A series of thermoplastic oligoimides with a propargyl substituent in the side chain was synthesized by the method of high-Temperature catalytic copolycondensation in the melt of benzoic acid based on the monomer 5-(2-propyn-1-yloxy) benzene-1,3-diamine (PBD), 2,2-bis-[(3,4-di-carboxyphenoxy)phenyl]propane dianhydride (BPADA), 2,2-bis-[(4-Aminophenoxy)phenyl]propane (BAPP) and phthalic anhydride (PA). The uncured imide oligomers showed good solubility (>20 wt% in N-methyl-2-pyrrolidone), wide temperature processing window (>50C) and also flow well at 220C. These imide oligomers were successfully converted to cross-linked structures after curing at 300C. Cross-linked oligomers have a temperature of 5% weight loss >500C and Tg >200C.

Transpositive Tandem Annulation of Phthalides with Allene Carboxylates: Regioselective Synthesis of Arylnaphthalene Lignans

Allene carboxylates, scarcely used as Michael acceptors, serve as acceptors in the annulation with phthalides in the presence of LDA and provide a one-pot synthesis of naphtho[c]furanones in very good yields. This tandem annulation is proposed to proceed via transposition of the hydroxy group resulting from the initial annulation.

Montmorillonite K-10 clay as reusable heterogeneous catalyst for the microwave-mediated solventless synthesis of phthalazinetetraones

Different phthalazino[2,3-b]phthalazine-5,7,12,14-tetraones were synthesized in a simple and environmentally benign method from the reaction of some phthalic anhydrides with semicarbazide or thiosemicarbazide using montmorillonite K-10 clay as solid heterogeneous acidic catalyst and microwaves under solvent-free conditions in good yields and short reaction times. The present method has many obvious advantages compared with those reported in the literature, including high efficiency, higher yield, operational simplicity, environmental benignity, and the possibility of recycling the solid clay. The solid clay catalyst used in the first cycle of the reactions was successfully recovered and reused in the second cycle, showing a gradual decrease in activity.

A Mild TEMPO-Catalyzed Aerobic Oxidative Conversion of Aldehydes into Nitriles

An efficient method to prepare nitriles from aldehydes using hexamethyldisilazane (HMDS) as the nitrogen source has been developed. The reactions were performed with 2,2,6,6-tetramethylpiperidine l-oxyl (TEMPO) as the catalyst, NaNO2 or TBN as the co-catalyst, and molecular oxygen as the terminal oxidant under mild conditions. A variety of aromatic, heteroaromatic, aliphatic and allylic aldehydes could be converted into their corresponding nitriles in good to excellent yields.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 1-Benzofuran-2-carbonitrile, you can also check out more blogs about41717-32-2

The Polycomb Repressor Complex 1 Drives Double-Negative Prostate Cancer Metastasis by Coordinating Stemness and Immune Suppression

The mechanisms that enable immune evasion at metastatic sites are poorly understood. We show that the Polycomb Repressor Complex 1 (PRC1) drives colonization of the bones and visceral organs in double-negative prostate cancer (DNPC). In vivo genetic screening identifies CCL2 as the top prometastatic gene induced by PRC1. CCL2 governs self-renewal and induces the recruitment of M2-like tumor-associated macrophages and regulatory T cells, thus coordinating metastasis initiation with immune suppression and neoangiogenesis. A catalytic inhibitor of PRC1 cooperates with immune checkpoint therapy to reverse these processes and suppress metastasis in genetically engineered mouse transplantation models of DNPC. These results reveal that PRC1 coordinates stemness with immune evasion and neoangiogenesis and point to the potential clinical utility of targeting PRC1 in DNPC. Su et al. show that PRC1 drives metastasis of androgen receptor and neuroendocrine double-negative prostate cancers by regulating CCL2 expression. CCL2 governs self-renewal and recruitment of TAM and Treg. PRC1 inhibition combined with immune checkpoint blockade reverses these processes and suppresses metastasis.
