Description
Sorafenib tosylate, also known as Nexavar, is a small molecular inhibitor of several kinases involved in tumor angiogenesis and proliferation. It targets Raf (IC50=12nM for Raf-1), VEGFR (IC50=90nM for VEGFR-2 and IC50=12nM for VEGFR-3), and platelet-derived growth factor receptor (IC50=57nM for PDGFR-b). Sorafenib tosylate blocks tumor progression by inhibiting cellular proliferation dependent on the activation of the MAPK pathway (Raf) and/or inhibiting tumor angiogenesis through VEGFR and/or PDGFR. It is a light yellow solid and is available under the brand names Nexavar (Bayer HealthCare) and Xarelto (Bayer HealthCare).
Uses
1. Used in Oncology:
Sorafenib tosylate is used as an antineoplastic agent for the treatment of advanced renal cell carcinoma and hepatocellular carcinoma. It targets multiple kinases, including RAF, VEGFR-2, VEGFR-3, PDGFR-β, KIT, and FLT-3, which are involved in tumor cell proliferation and tumor angiogenesis.
2. Used in Phase III Trials:
Sorafenib tosylate is being jointly developed by Bayer and Onyx in phase III trials as a single agent for the treatment of advanced hepatocellular carcinoma and in combination with carboplatin and paclitaxel for patients with advanced metastatic melanoma.
3. Used in Phase II Trials:
Sorafenib tosylate is under investigation in phase II trials in combination with doxorubicin for the treatment of advanced hepatocellular carcinoma. Additional phase II trials are ongoing for non-small cell lung cancer (NSCLC) and in postmenopausal women with estrogen receptor and/or progesterone receptor-positive metastatic breast cancer.
4. Used in National Cancer Institute (NCI) Trials:
The NCI is evaluating Sorafenib tosylate both as a single therapy agent and in combination with other oncology agents in phase II trials for several cancer indications.
Indications
It is indicated for the treatment of hepatocellular carcinoma and the treatment of advanced renal cell carcinoma (primary kidney cancer).
Indications
Sorafenib (Nexavar(R), Bayer) was the first approved inhibitor targeting the vascular endothelial growth factor (VEGF) family kinases, which include VEGFR1, VEGR2, and VEGFR3. Sorafenib was originally approved for the treatment of renal cell carcinoma (RCC) in 2005, hepatocellular carcinoma in 2007, and locally recurrent or metastatic thyroid carcinoma refractory to radioactive iodine treatment in 2013. Six other approved inhibitors with VEGFRs as the main targets are sunitinib (Sutent(R), Pfizer) for RCC, soft tissue sarcoma, thyroid cancer,metastatic pancreatic tumors, gastrointestinal stromal tumor, and several other types of carcinomas; pazopanib (Votrient(R), GlaxoSmithKline) for RCC, soft tissue sarcoma, and thyroid cancer; axitinib (Inlyta(R), Pfizer) for RCC,thyroid cancer, and aplastic anemia, as well as T315I-mutant Bcr–Abl1-driven leukemia; regorafenib (Stivarga(R), Bayer) for gastrointestinal stromal tumors and colorectal cancer; nintedanib (Ofev(R), Boehringer Ingelheim) for the non-oncological indication of idiopathic pulmonary fibrosis; and lenvatinib (Lenvima(R), Eisai Inc.) for RCC and different types of thyroid cancers. Sunitinib, pazopanib, and lenvatinib bind to the “DFG-in”conformation of VEGFRs, while axitinib, regorafenib, and nintedanib bind to inactive VEGFRs adopting the “DFG-out”conformation.
Mechanism of action
The bi-aryl urea sorafenib is an oral multikinase inhibitor that inhibits both cell surface tyrosine kinase receptors and downstream intracellular serine/threonine kinases in the Ras/MAPK cascade.[2-4] Receptor tyrosine kinases inhibited by sorafenib include vascular endothelial growth factor receptor (VEGFR)-1, VEGFR-2, VEGFR-3, platelet-derived growth factor receptor (PDGFR)-b, c-KIT, FMS-like tyrosine kinase 3 (FLT-3) and RET. Intracellular Raf serine/threonine kinase isoforms inhibited by sorafenib include Raf-1 (or C-Raf), wild-type B-Raf and mutant B-Raf.[3, 4] These kinases are involved in tumour cell proliferation and tumour angiogenesis.[3, 4]
The antiproliferative activity of sorafenib is variable in different tumor types and largely depends on the oncogenic signaling pathways that mediate tumor proliferation. Sorafenib has also been shown to induce apoptosis in several tumor cell lines. Although the mechanism through which sorafenib induces apoptosis is not fully elucidated and may vary between cell lines, a commonly observed theme is the inhibition of phosphorylation of the initiation factor eIF4E and loss of the antiapoptotic protein myeloid cell leukemia-1 (MCL-1)[5]. Recently, sorafenib was shown to inhibit hepatitis C viral replication in vitro[6], and in vitro studies have also shown some direct effects on immune cells [7]. Whether these effects

Synthesis
An improved, four-step synthesis in 63% overall yield
was published recently and is illustrated in the scheme.
Picolinic acid (127) was heated with Vilsmeier reagent for
16 hr to give 128 in 89% yield as an off-white solid. The
acid chloride 128 was treated with methylamine in methanol
at low temperature to give amide 129 in 88% yield as paleyellow
crystals after its crystallization from ethyl acetate.4-Aminophenol anion was generated under a basic condition
and compound 129 was added to the anion solution to give
corresponding addition compound 131 in 87% yield. For an
unknown reason, potassium carbonate used in the reaction
increased the reaction rate significantly. Finally, compound
131 was condensed with isocyanate 132 in methylene chloride
to give sorafenib (XVIII) in 92% yield as a white solid.
Drug interactions
Potentially hazardous interactions with other drugs
Anticoagulants: may enhance effect of coumarins.
Antipsychotics: avoid with clozapine (increased risk
of agranulocytosis).
Antivirals: avoid with boceprevir.
Metabolism
Sorafenib is metabolised primarily in the liver and
undergoes oxidative metabolism mediated by CYP3A4,
as well as glucuronidation mediated by UGT1A9. 8
metabolites have been identified, during in vitro studies
one has been shown to have equal activity to sorafenib.
About 96% of a dose is excreted within 14 days, with
77%, mostly as unchanged drug, recovered in the faeces,
and 19% in the urine as glucuronidated metabolites.

Sorafenib tosylate (SORt) is an oral multikinase inhibitor used for treatment of advanced renal cell, liver, and thyroid cancers. In this study, this drug was synthesized and its antiproliferative activities against HCT116 and CT26 cells were assessed. The interaction of SORt with β-lactoglobulin (BLG) was studied using different fluorescence techniques, circular dichroism (CD), zeta potential measurements, and docking simulation. The results of infrared (IR), mass, HNMR, and CNMR spectra demonstrated that the drug was produced with high quality, purity, and efficiency. SORt showed potent cytotoxicity against HCT116 and CT26 cells with IC50 of 8.12 and 5.42 μM, respectively. For BLG binding of SORt, the results showed that static quenching was the cause of the high affinity drug–protein interaction. Three-dimensional fluorescence and synchronous spectra indicated that SORt conformation was changed at different levels. CD suggested that the α-helix content remained almost constant in the BLG–SORt complex, whereas random coil content decreased. Zeta potential values of BLG were more positive after binding with SORt, due to electrostatic interactions between BLG and SORt. Thermodynamic parameters confirmed van der Waals and hydrogen bond interactions in the complex formation. Molecular modelling predicted the presence of hydrogen bonds and electrostatic forces in the BLG–SORt system, which was consistent with the experimental results.
Catalytic Decarboxylative C?N Formation to Generate Alkyl, Alkenyl, and Aryl Amines

Transition-metal-catalyzed sp2 C?N bond formation is a reliable method for the synthesis of aryl amines. Catalytic sp3 C?N formation reactions have been reported occasionally, and methods that can realize both sp2 and sp3 C?N formation are relatively unexplored. Herein, we address this challenge with a method of catalytic decarboxylative C?N formation that proceeds through a cascade carboxylic acid activation, acyl azide formation, Curtius rearrangement and nucleophilic addition reaction. The reaction uses naturally abundant organic carboxylic acids as carbon sources, readily prepared azidoformates as the nitrogen sources, and 4-dimethylaminopyridine (DMAP) and Cu(OAc)2 as catalysts with as low as 0.1 mol % loading, providing protected alkyl, alkenyl and aryl amines in high yields with gaseous N2 and CO2 as the only byproducts. Examples are demonstrated of the late-stage functionalization of natural products and drug molecules, stereospecific synthesis of useful α-chiral alkyl amines, and rapid construction of different ureas and primary amines.
