Farnesyl pyrophosphate synthase inhibitors with antiosteoporosis efficacy in ovariectomized rats: A mixed binding approach beyond bisphosphonates. Eur J Med Chem 2024; 276:116679. [PMID: 39018923 DOI: 10.1016/j.ejmech.2024.116679] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2024] [Revised: 07/09/2024] [Accepted: 07/12/2024] [Indexed: 07/19/2024]
Abstract
The primary focus of bisphosphonate medications is on targeting human farnesyl pyrophosphate synthase (hFPPS), an essential regulator of mammalian isoprenoids. Yet, these drugs encounter limitations due to their restricted "druglike" properties and their effectiveness primarily in treating skeletal disorders. In this study, we synthesized novel non-bisphosphonate compounds, using 4,4'-(ethane-1,2-diylbis(oxy))bis(3-methoxybenzaldehyde) (1) as a starting compound, with the aim of targeting hFPPS through a mixed binding approach. Among the various compounds tested, compounds 4a and 4b exhibited significant inhibition of hFPPS activity, with IC50 values of 1.108 and 1.24 μM, respectively. Docking studies further revealed that both compounds bound within the allylic binding site and near the isopentenyl diphosphate (IPP) site within the hFPPS pocket. Molecular dynamic simulations were performed on the best docking pose of the most potent compound 4a to confirm the formation of a stable complex with hFPPS. In an in vivo study conducted on ovariectomized rats, various biochemical markers including osteocalcin, estradiol, osteoprotegerin, bone mineral content, and density were negatively impacted, while levels of bone specific alkaline phosphatase, receptor activator of nuclear factor kappa-Β ligand, serum/urinary calcium, and phosphate increased. Notably, compound 4a exhibited antiresorptive properties similar to zoledronate, effectively restoring most of the perturbed biochemical estimations. These findings suggest the potential of compound 4a, a non-bisphosphonate compound, as alternative therapeutic agents for combating osteoporosis.

Abstract
A new method for the preparation of the underrepresented 1,5-dimethyl-6-thioverdazyl radicals has been developed employing Lawesson's reagent (LR). The synthetic route involves the direct thionation of the carbonyl group of the corresponding dialkylbishydrazone followed by cyclization to give the tetrazinanthione verdazyl precursor on a gram scale. Subsequent oxidation yields the 6-thioverdazyl radical. It was determined that thionation of substrates containing electron-withdrawing groups in the ortho- or para-positions was high yielding. In contrast, for the parent phenyl group or substrates bearing weakly electron-donating substituents, thionation efficiency was significantly reduced. This could be overcome by utilizing partial in situ cyclization, which occurs during work up, to generate the tetrazinanthione directly via a one-pot synthesis. Density functional theory suggests that the LR fragment interacts with the carbonyl prior to cycloaddition and subsequent to cycloreversion, leading to the thiocarbonyl. The electronic nature of the radical is characterized with electron paramagnetic resonance as well as the first report of 6-thioverdazyl redox properties.

Abstract
Azlactones and thiazoles are common structural motifs and possess diverse applications. A new method for the efficient and straightforward syntheses of 2,4-disubstituted thiazoles from azlactones has been developed. The reaction proceeded via deoxygenation of azlactones by Lawesson's reagent without metal or external additives. A variety of 2,4-disubstituted thiazoles were synthesized with up to 92% yield. Furthermore, the importance of this methodology was also justified by a gram-scale synthesis.

Abstract
Lawesson's reagent (LR) is a well-known classic example of a compound with unique construction and unusual chemical behavior, with a wide range of applications in synthetic organic chemistry. Its main functions were rounded for the thionation of various carbonyl groups in the early days, with exemplary results. However, the role of Lawesson's reagent in synthesis has changed drastically, and now its use can help the chemistry community to understand innovative ideas. These include constructing biologically valuable heterocycles, coupling reactions, and the thionation of natural compounds. The ease of availability and the convenient usage of LR as a thionating agent made us compile a review on the new diverse applications on some common functional groups, such as ketones, esters, amides, alcohols, and carboxylic acids, with biological applications. Since the applications of LR are now diverse, we have also included some new classes of heterocycles such as thiazepines, phosphine sulfides, thiophenes, and organothiophosphorus compounds. Thionation of some biologically essential steroids and terpenoids has also been compiled. This review discusses the recent insights into and synthetic applications of this famous reagent from 2009 to January 2021.

Abstract
After completing the thio-substitution with Lawesson’s reagent, ethanol was found to be effective in the decomposition of the inherent stoichiometric six-membered-ring byproduct from the Lawesson’s reagent to a highly polarized diethyl thiophosphonate. The treatment significantly simplified the following chromatography purification of the desired thioamide in a small scale preparation. As scaling up the preparation of two pincer-type thioamides, we have successfully developed a convenient process with ethylene glycol to replace ethanol during the workup, including a traditional phase separation, extraction, and recrystallization. The newly developed chromatography-free procedure did not generate P-containing aqueous waste, and only organic effluents were discharged. It is believed that the optimized procedure offers the great opportunity of applying the Lawesson’s reagent for various thio-substitution reactions on a large scale.

Abstract
A thionation reaction was performed on some chiral flavanones using Lawesson's reagent (LR) and leads to the formation of new chiral thiocarbonyl flavanes. LR in this thionation reaction with Hesperetin and Naringenin gives new flavan-4-thiones with yields ranged between 41 and 52%. Based on the Wittig reaction principle, LR is currently the most widely used reagent for this type of reaction. Enantiomeric separation by high-performance liquid chromatography methods was then set-up using three different polysaccharide-based chiral stationary phases (CSPs). Chiral separations were successfully accomplished with high resolution (1.22 ≤ Rs ≤ 5.23). The chiral discrimination mechanism(s) between the analytes under study, mobile phase, and the CSPs were discussed.
