- Structure-Based Design and Synthesis of Piperidinol-Containing Molecules as New Mycobacterium abscessus Inhibitors
-
Non-tuberculous mycobacterium (NTM) infections, such as those caused by Mycobacterium abscessus, are increasing globally. Due to their intrinsic drug resistance, M. abscessus pulmonary infections are often difficult to cure using standard chemotherapy. We previously demonstrated that a piperidinol derivative, named PIPD1, is an efficient molecule both against M. abscessus and Mycobacterium tuberculosis, the agent of tuberculosis, by targeting the mycolic acid transporter MmpL3. These results prompted us to design and synthesize a series of piperidinol derivatives and to determine the biological activity against M. abscessus. Structure-activity relationship (SAR) studies pointed toward specific sites on the scaffold that can tolerate slight modifications. Overall, these results identified FMD-88 as a new promising active analogue against M. abscessus. Also, we determined the pharmacokinetics properties of PIPD1 and showed that intraperitoneal administration of this compound resulted in promising serum concentration and an elimination half-life of 3.2 hours.

- Analogs of penfluridol as chemotherapeutic agents with reduced central nervous system activity
-
Several recent reports have highlighted the feasibility of the use of penfluridol, a well-known antipsychotic agent, as a chemotherapeutic agent. In vivo experiments have confirmed the cytotoxic activity of penfluridol in triple-negative breast cancer model, lung cancer model, and further studies have been proposed to assess its anticancer activity and viability for the treatment of glioblastomas. However, penfluridol anticancer activity was observed at a dosage significantly higher than that administered in antipsychotic therapy, thus raising the concern for the potential onset of CNS side effects in patients undergoing intensive pharmacological treatment. In this study, we evaluate the potential CNS toxicity of penfluridol side by side with a set of analogs.

- Penfluridol preparation method
-
The invention discloses a penfluridol preparation method. The penfluridol preparation method includes the following steps of 1), subjecting succinic anhydride and fluorobenzene to Friedel-Crafts reaction prior to acid decomposition, and collecting a compound from the formula 2) as is shown in the description; 2), putting the compound in a solvent to collect a compound in formula 3) as is shown in the description in a solvent reduced through a reducing agent; 3), putting the compound into the fluorobenzene to perform the Friedel-Crafts reaction to collect a compound in the formula 4) as is shown in the description; subjecting the compound and ethyl chloroformate to action to generate a compound in formula 5) as is shown in the description; 5), subjecting the compound and a compound shown in formula (XVII) to reaction prior to hydrolyzation to collect a compound in formula 6) as is shown in the description; 6), performing reduction with the reducing agent prior to hydrolyzing a reduction product and then collecting penfluridol (I). The penfluridol preparation method is high in yield, low in cost, moderate in reaction condition, short in circuit, proper for industrial production, low in three wastes, easy to treat and suitable for industrial production.

- Synthesis and SAR study of diphenylbutylpiperidines as cell autophagy inducers
-
A novel series of diphenylbutylpiperidines as autophagy inducers was described and extensive SAR studies resulted in derivatives (15d-e, 15i-j) with 10-fold greater activity than the lead compounds 1 and 2. Meanwhile, a new synthetic route to diphenylbutyl bromide (6) from bromobenzene and γ-butyrolactone was also reported here.
