MEBENDAZOLE POLYMORPH FOR TREATMENT AND PREVENTION OF TUMORS
-
, (2016/09/22)
Mebendazole is an antiparasitic drug with over 40 years of safe use. Recently mebendazole was repurposed for glioblastoma therapy. Three polymorphs of mebendazole exist, but the relative polymorph content for existing drugs varies, and the therapeutic anti-cancer relevance of the different polymorphs was unknown. As an oral drug mebendazole polymorph C is a superior form, and it reaches the brain and brain tumors in effective concentrations. Efficacy is further improved by combining mebendazole with a P-glycoprotein inhibitor. Mebendazole may also be used for therapy of other cancers, as well as a chemo-preventative agent.

Paragraph 0064-0066, (2017/06/14)
A preparing method of a mebendazole intermediate (3,4-diaminophenyl)phenyl methanone is disclosed. The method includes adding 4-amino-3-nitro diphenylmethanone and a catalyst into an organic solvent, adding a hydrogen donor, and performing transfer hydrogenation reduction to obtain the (3,4-diaminophenyl)phenyl methanone, wherein the catalyst is a Pd-X/C catalyst, and the X is one of Ni, Ru, La, Ce, Co, Li, K, Mg, Ti, Cu or Mo. The method has advantages of mild conditions, simple operation, a high reduction rate, a low cost, high environment protection performance, easy industrial production, and the like.

Sodium taurocholate cotransporting polypeptide (NTCP) is a multiple transmembrane transporter predominantly expressed in the liver, functioning as a functional receptor for HBV. Through our continuous efforts to identify NTCP as a novel HBV target, we designed and synthesized a series of new compounds based on the structure of our previous compound NT-5. Molecular docking and MD simulation validated that a new compound named NTI-007 can tightly bind to NTCP, whose efficacy was also measured in vitro virological examination and cytotoxicity studies. Furthermore, autophagy was observed in NTI-007 incubated HepG2.2.15 cells, and results of q-PCR and Western blotting revealed that NTI-007 induced autophagy through NTCP-APOA1-HBx-Beclin1-mediated pathway. Taken together, considering crucial role of NTCP in HBV infection, NTCP-mediated autophagic pathway may provide a promising strategy of HBV therapy and given efficacy of NTI-007 triggering autophagy. Our study suggests pre-clinical potential of this compound as a novel anti-HBV drug candidate.

Albendazole (Abz) and Mebendazole (Mbz) analogues have been synthesized and in vitro tested against the protozoa Giardia lamblia, Trichomonas vaginalis and the helminths Trichinella spiralis and Caenorhabditis elegans. Results indicate that compounds 4a, 4b (Abz analogues), 12b and 20 (Mbz analogues) are as active as antiprotozoal agents as Metronidazole against G. lamblia. Compound 9 was 58 times more active than Abz against T. vaginalis. Compounds 8 and 4a also shown high activity against this protozoan. Compounds 4b and 5a were as active as Abz. None of the Mbz analogues showed activity against T. vaginalis. The anthelmintic activity presented by these compounds was poor.
6-Lithioquinoxalines and Their Transformations

6-Bromo-2,3-diphenylquinoxaline reacts with butyllithium to give the 6-lithio derivative in a yield of more than 80%, which reacts with electrophiles such as benzophenone, Michler ketone, methyl ethyl ketone, iodine, selenium, and dimethylformamide to give the corresponding quinoxaline derivatives. 6-Bromo-2,3-dimethylquinoxaline is metallated with butyl- and phenyllithium at the methyl groups and benzene ring. These organolithium compounds react with benzophenone to give the corresponding diphenyl- and triaryl-carbinols, whose yield and ratio were determined by HPLC. These results open prospects for preparing new quinoxaline derivatives substituted at the annelated benzene ring.

Process for the manufacture of benzimidazolones-(2) wherein an o-phenylenediamine is reacted with optionally alkylated urea in the ratio of 1 to 1.3 moles per mole o-phenylenediamine in an organic solvent which has a solubility in water of not more than 5 g/l and has a boiling point above 100° C, at a temperature between 100° and 200° C.

A series of alkyl-(5-acyl-l-H-benzimidazol-2-yl)-carbamates were prepared and screened for anthelminthic activity. Some of them were found to be fully active at low, atoxic oral dose levels against gastro-intestinal nematodes. The activity against Syphacia muris and Strongyloides ratta is indicated. From these studies methyl (5-benzoyl-1-H-benzimidazol-2-yl) carbamate (mebendazole) and methyl [5-(4-fluorobenzoyl)-1-H-benzimidazol-2-yl]carbamate (flubendazole) were selected for detailed investigation.
