Remeur, Camille;Kelly, Christopher B.;Patel, Niki R.;Molander, Gary A. research published 《 Aminomethylation of Aryl Halides Using α-Silylamines Enabled by Ni/Photoredox Dual Catalysis》, the research content is summarized as follows. In the presence of the ruthenium photocatalyst [Ru(bipy)₃](PF₆^–)₂ and the nickel catalyst [Ni(dtbpy)(OH₂)₄]Cl₂ (dtbpy = 4,4′-di-tert-butyl-2,2′-bipyridine), aryl bromides and iodides such as 4-bromobenzonitrile underwent chemoselective aminomethylation reactions with aminomethylsilanes such as 1-(dimethylphenylsilylmethyl)piperidine in DMF under irradiation with blue LED for 24-36 h at ambient temperature to yield benzylic amines such as 4-(1-piperidinylmethyl)benzonitrile in 41-70% yields. The low oxidation potential of the silylmethyl amines enabled facile single electron transfer (SET) oxidation of the amine followed by rapid desilylation; the resultant α-amino radicals were competent to undergo nickel-mediated cross-coupling with aryl bromides and iodides.

Razmiene, Beatrice;Reznickova, Eva;Dambrauskiene, Vaida;Ostruszka, Radek;Kubala, Martin;Zukauskaite, Asta;Krystof, Vladimir;Sackus, Algirdas;Arbaciauskiene, Egle research published 《 Synthesis and Antiproliferative Activity of 2,4,6,7-Tetrasubstituted-2H-pyrazolo[4,3-c]pyridines》, the research content is summarized as follows. A library of 2,4,6,7-tetrasubstituted-2H-pyrazolo[4,3-c]pyridines was prepared from easily accessible 1-phenyl-3-(2-phenylethynyl)-1H-pyrazole-4-carbaldehyde via an iodine-mediated electrophilic cyclization of intermediate 4-(azidomethyl)-1-phenyl-3-(phenylethynyl)-1H-pyrazoles to 7-iodo-2,6-diphenyl-2H-pyrazolo[4,3-c]pyridines followed by Suzuki cross-couplings with various boronic acids and alkylation reactions. The compounds were evaluated for their antiproliferative activity against K562, MV4-11, and MCF-7 cancer cell lines. The most potent compounds displayed low micromolar GI₅₀ values. 4-(2,6-Diphenyl-2H-pyrazolo[4,3-c]pyridin-7-yl)phenol proved to be the most active, induced poly(ADP-ribose) polymerase 1 (PARP-1) cleavage, activated the initiator enzyme of apoptotic cascade caspase 9, induced a fragmentation of microtubule-associated protein 1-light chain 3 (LC3), and reduced the expression levels of proliferating cell nuclear antigen (PCNA). The obtained results suggest a complex action of 4-(2,6-diphenyl-2H-pyrazolo[4,3-c]pyridin-7-yl)phenol that combines antiproliferative effects with the induction of cell death. Moreover, investigations of the fluorescence properties of the final compounds revealed 7-(4-methoxyphenyl)-2,6-diphenyl-2H-pyrazolo[4,3-c]pyridine as the most potent pH indicator that enables both fluorescence intensity-based and ratiometric pH sensing.

An isocratic RP-HPLC was developed and validated for isolation of 1′-Acetoxychavicol acetate (ACA) from Alpinia galanga extract (AGE). Nucleodur C18 column was used as the stationary phase and mixture of acetonitrile/0.1% formic acid in water (60/40, volume/volume) were used as mobile phase. The elution was carried out with a flow rate of 1 mL/min. Further, the method was validated as per ICH Q2 [R1] guidelines in terms of linearity, LOD, LOQ, recovery, precision and specificity. The validated method was utilized for two purposes i.e. optimizing the isolation of ACA from AGE and quantifying ACA′s concentration and release from its nanoemulsion. To achieve high yield of ACA, Central composite design (CCD) was used to optimize sieve number and solid to solvent ratio. The retention time of standard and isolated ACA were found at 5.63 min and 5.46 min resp. The results indicated that the validated method was linear, accurate, precise and specific. During optimization, excellent correlation was observed between practical yield (3.89 ± 0.23% weight/weight of dried rhizomes) and predicted yield (3.73% weight/weight of dried rhizomes) of ACA with p value more than 0.05. The percentage of ACA loaded in the nanoemulsion was found to be 99.12 ± 0.39. The in vitro diffusion studies showed 90.12 ± 2.21% release of ACA at the end of 24 h. It was concluded that the validated method has been successfully utilized to isolate the ACA from AGE and quantify the amount of ACA present in nanoemulsion.

Raju, Marina;Kunde, Shalvi Sinai;Auti, Sandip T.;Kulkarni, Yogesh A.;Wairkar, Sarika research published 《 Berberine loaded nanostructured lipid carrier for Alzheimer’s disease: Design, statistical optimization and enhanced in vivo performance》, the research content is summarized as follows. Berberine, an isoquinoline alkaloid, is reported for the treatment of Alzheimer’s disease. Despite having substantial therapeutic potential, it exhibits poor absorption, low oral bioavailability and limited penetration in the brain. In this study, berberine-loaded nanostructured lipid carriers (Berb-NLCs) were developed by melt-emulsification and ultrasonication using Geleol, Miglyol 812 N, Solutol HS 15 as a solid lipid, liquid lipid and surfactant, resp. The Berb-NLC formulation was statistically optimized by a 32 factorial design in which the effect of surfactant and berberine concentration was assessed on particle size and entrapment efficiency of Berb-NLCs. Optimized Berb-NLCs (Trial-5) exhibited particle size of 186 nm, polydispersity index of 0.108, the zeta potential of -36.86 mV and 88% entrapment efficiency. The in vitro release of berberine from Batch-B5 was 82% in phosphate buffer at the end of 24 h. The comparative results of pharmacodynamic studies involving behavioral assessment by locomotor activity, passive avoidance test, elevated plus maze test and spatial memory assessment by Morris water maze demonstrated improved behavioral parameters in vivo by Berb-NLCs compared to pure berberine in Albino Wistar rats. Thus, berberine-loaded nanostructured lipid carriers have the potential of brain targeting and were effective in an animal model of Alzheimer’s disease.

Rajamma, Sreeranjini Sukumaran;Krishnaswami, Venkateshwaran;Prabu, Sakthivel Lakshmana;Kandasamy, Ruckmani research published 《 Geophila repens phytosome-loaded intranasal gel with improved nasal permeation for the effective treatment of Alzheimer′s disease》, the research content is summarized as follows. Geophila repens (L.) I. M. Johnst is a creeping herb with good anti-cholinesterase activity and has been used traditionally in India to improve memory and intelligence for many years. The antioxidant activity of the ′methanolic extract of the leaves of Geophila repens′ (MEGR) was determined and found to be high, possibly due to the presence of phenolic compounds, flavonoids, and triterpenoids. The permeation of phytoconstituents through the blood-brain barrier is a challenging factor in the development of phytoformulation for the treatment of Alzheimer′s disease (AD). To overcome these limitations, ′Geophila repens phytosome-loaded intranasal gel′ (MEGR-PG) with enhanced permeation properties through the nasal route to the brain was developed. Here, transcutol was used as permeation enhancer and hydroxypropyl methylcellulose as a gelling agent. For the development of MEGR-PG, a screened phytosome (MEGR: soy phosphatidylcholine, 1: 2) with a particle size of 444.93 ± 25.24 nm, PDI value of 0.358 ± 0.012, spherical morphol., encapsulation efficiency of 51.88 ± 1.025% with an immediate in vitro release of 45.84 ± 5.6% at 60 min followed by a maintenance period of up to 480 min was used. MEGR-PG exhibited significant in vitro nasal mucosa permeation without causing skin irritation. Furthermore, MEGR-PG exhibited a similar proportion of acetylcholinesterase inhibition (97.87 ± 6.84%) in comparison to donepezil (97.17 ± 4.86%) but was greater than MEGR (69.86 ± 5.68%), and it also accelerated angiogenesis, which shows potential to modify the cognitive behavior of AD patients. In addition, the brain targeting effect of MEGR-PG has been confirmed by a preclin. in vivo imaging study. As a result, MEGR-PG is a promising treatment option for AD patients.

Qu, Biao;Wang, Xiao-lin;Zheng, De-chong;Mai, Chu-tian;Liu, Zhong-qiu;Zhou, Hua;Xie, Ying research published 《 Novel treatment for refractory rheumatoid arthritis with total glucosides of paeony and nobiletin codelivered in a self-nanoemulsifying drug delivery system》, the research content is summarized as follows. Patients with refractory rheumatoid arthritis (RA) remain a substantial clin. problem, while the overexpression of P-glycoprotein (P-gp) on their lymphocytes may contribute to resistance to anti-rheumatic drugs. This study aims to develop a novel treatment for refractory RA consisting of the combination of total glucosides of paeony (TGPs) and the P-gp inhibitor nobiletin (N), which are codelivered in a self-nanoemulsifying drug delivery system (SNEDDS). Based on the solubility, compatibility, and pseudoternary phase diagram tests, a nano-SNEDDS formulation composed of capryol 90-cremophor EL35-tcranscutol HP (CET) to codeliver TGP and N was developed, and this formulation increased the bioavailability of TGP by 435.04% (indicated with paeoniflorin). A modified adjuvant-induced arthritis (AIA) rat model was verified for the overexpression of P-gp in lymphocytes and resistance to methotrexate (MTX) treatment at the reported anti-inflammatory dosage. CET formulation not only increased the solubility and permeability of TGP but also inhibited the function and expression of P-gp, leading to enhanced bioavailability and intracellular concentration in the lymphocytes of AIA rats and consequently boosting the anti-arthritic effects of TGP. Moreover, TGP and N coloaded CET reduced the expression of P-gp in AIA rats partly by inhibiting the phosphorylated AKT and HIF-1α pathways. In summary, TGP-N coloaded SNEDDS is a novel and effective treatment for refractory RA.
