Bioorg Chem 2024; 147:107391. [PMID: 38677010 DOI: 10.1016/j.bioorg.2024.107391] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 04/15/2024] [Accepted: 04/20/2024] [Indexed: 04/29/2024]
Abstract
Apoptosis signal regulated kinase 1 (ASK1, MAP3K5) is a member of the mitogen activated protein kinase (MAPK) signaling pathway, involved in cell survival, differentiation, stress response, and apoptosis. ASK1 kinase inhibition has become a promising strategy for the treatment of Non-alcoholic steatohepatitis (NASH) disease. A series of novel ASK1 inhibitors with indazole scaffolds were designed and synthesized, and their ASK1 kinase activities were evaluated. The System Structure Activity Relationship (SAR) study discovered a promising compound 33c, which has a strong inhibitory effect on ASK1. Noteworthy observations included a discernible reduction in lipid droplets within LO2 cells stained with Oil Red O, coupled with a decrease in LDL, CHO, and TG content within the NASH model cell group. Mechanistic inquiries revealed that compound 33c could inhibit the protein expression levels of the upregulated ASK1-p38/JNK signaling pathway in TNF-α treated HGC-27 cells and regulate apoptotic proteins. In summary, these findings suggest that compound 33c may be valuable for further research as a potential candidate compound against NASH.

Abstract
Five new alkylaluminum complexes with different pyridinyl-substituted imines or cyclohexyl-substituted imines were synthesized and characterized successfully. The aluminum complex [FlCHNCH(CH3)Py]AlMe2(Py = 2-pyridyl) (1) was obtained by reacting 9-[2-pyridyl-CH(CH3)-NCH]Fl (Fl = fluorenyl) (L1) and equimolar AlMe3. The reactions of 9-(2-pyridyl-NCH)Fl (L2) and 9-[2-N(CH3)2-cyclohexyl-NCH]Fl (L3) with equimolar AlMe3 or AlEt3 afforded other alkylaluminum complexes [FlCHNPy]AlMe2(Py = 2-pyridyl) (2), [FlCHNPy]AlEt2 (Py = 2-pyridyl) (3), [FlCHNCyN(CH3)2]AlMe2 (Cy = 2-cyclohexyl) (4) and [FlCHNCyN(CH3)2]AlEt2 (Cy = 2-cyclohexyl) (5). All these complexes (1-5) were characterized using NMR spectroscopy, elemental analysis, and X-ray crystal structure analysis. The catalytic properties of these new alkylaluminum complexes for the hydrophosphonylation of aldimines were examined. Complex 5 showed the best catalytic performance under mild reaction conditions with a low catalyst loading (1 mol%), and 20 different substituents of aldimines were isolated with more than 90% yields.

Abstract
A practical approach to α-aminophosphonates has been developed through an In(OTf)3-catalyzed N-α phosphonylation of N,O-acetals with triethyl phosphite 7. Indoline and isoindoline N,O-acetals 6a-6j and 9a-9j and chain N,O-acetals 11a-11p were subjected to a Lewis acid catalyzed N-α phosphonylation process. As a result, the desired α-aminophosphonates 8a-8j, 10a-10j and 12a-12p were obtained in moderate to good yields.

Abstract
We reported a new method dealing with the synthesis of novel pharmacologically relevant α-aminophosphonate derivatives via a lipase-catalyzed Kabachnik−Fields reaction with yields of up to 93%. The advantages of this protocol are excellent yields, mild reaction conditions, low costs, and sustainability. The developed protocol is applicable to a range of H-phosphites and organic amines, providing a wide substrate scope. A new class of α-aminophosphonate analogues possessing P-chiral centers was also synthesized. The synthesized compounds were characterized on the basis of their antimicrobial activities against E. coli. The impact of the various alkoxy groups on antimicrobial activity was demonstrated. The crucial role of the substituents, located at the aromatic rings in the phenylethyloxy and benzyloxy groups, on the inhibitory action against selected pathogenic E. coli strains was revealed. The observed results are especially important because of increasing resistance of bacteria to various drugs and antibiotics.

Abstract
The dramatic rise in drug resistance accelerated the desire for new antibacterial agents to safeguard human health. This work constructed a novel type of aloe emodin-hybridized sulfonamide aminophosphates as unique potential antibacterial agents. The biological assay revealed that some target hybrids possessed potent inhibitory activity. Particularly, ethyl aminophosphate-hybridized sulfadiazine aloe emodin 7a (EASA-7a) not only displayed preponderant antibacterial efficiency against drug-resistant E. faecalis at low concentration as 0.25 μg/mL but also possessed strong bacteriostatic capacity and low propensity to develop resistance toward E. faecalis. The weak hemolysis toward human red blood cells and efficient biofilm-disruptive ability further implied the therapeutic potential of EASA-7a. Preliminary studies disclosed that the excellent antibacterial behavior of EASA-7a might be attributed to its capacity to permeate and depolarize the bacterial membrane, as well as promote ROS accumulation and intercalate with DNA. These findings manifested that EASA-7a was worthy of further development to combat life-threatening bacterial infections.

Abstract
An efficient method for the synthesis of a new class of α-aminophosphonates of imatinib derivative has been developed in one-pot Kabachnik-Fields reaction of N-(5-amino-2-methyl phenyl)-4-(3-pyridyl)-2-pyrimidine amine with various aldehydes and diethyl phosphite under microwave irradiation and neat conditions using NiO nanoparticles as an reusable and heterogeneous catalyst, with 96% yield at 450 W within 15 min. All the compounds were evaluated for their in vitro cytotoxicity with various cancer cell lines by MTT assay method. Compounds with halo (4f, -4Br, IC50 = 1.068 ± 0.88 µM to 2.033 ± 0.97 µM), nitro substitution (4 h, -3NO2, IC50 = 1.380 ± 0.94 µM to 2.213 ± 0.64 µM), (4 g, -4NO2, IC50 = 1.402 ± 0.79 µM to 2.335 ± 0.73 µM) and (4i, 4-Cl, 3-NO2, IC50 = 1.437 ± 0.92 µM to 2.558 ± 0.76 µM) were showed better anticancer activity when compared with standard drugs Doxorubicin and Imatinib using MTT assay method. Further in silico target hunting reveals the anticancer activity of the designed compounds by inhibiting human ABL tyrosine kinase and all the designed compounds have shown significant drug-like characteristics.

Abstract
Rhodotorula mucilaginosa was successfully applied as a biocatalyst for the enantioselective resolution of the racemic mixtures of heteroatom phosphonates derivatives, resulting in receiving the following enantiomers: (S)-1-amino-1(2-thienyl)methylphosphonic acid (Product 1) and (R)-1-amino-1-(3'pirydyl) methylphosphonic acid (Product 2). Biological synthesis of both products is reported for the first time. Pure (S)-1-amino-1-(2-thienyl)methylphosphonic acid (Product 1) was isolated with a conversion degree of 50% after 24 h of biotransformation was conducted on a laboratory scale under moderate conditions (1.55 mM of substrate 1, 100 mL of distilled water, 135 rpm, 25°C; Method A). The scale was enlarged to semi-preparative one, using a simplified flow-reactor (Method C; 3.10 mM of substrate 1) and immobilized biocatalyst. The product was isolated with a conversion degree of 50% just after 4 h of biotransformation. Amino-1-(3'pirydyl)methylphosphonic acid (Substrate 2) was converted according to novel procedure, by the immobilized biocatalyst - Rhodotorula mucilaginosa. The process was carried out under moderate conditions (3.19 mM - substrate 2 solution; Method C1) with the application of a simplified flow reactor system, packed with the yeasts biomass entrapped in 4% agar-agar solution. Pure (R)-amino-1-(3'pirydyl)methylphosphonic (50% of conversion degree) was received within only 48 h.

Abstract
Multicomponent phosphonylation is accomplished upon the reaction of an imine with an aryne generated in situ in the presence of a dialkyl phosphite. This transition-metal-free protocol shows a broad substrate scope, providing a variety of α-aminophosphonates in moderate to good yields. A plausible mechanism for the reaction is proposed based on a deuterium exchange experiment.

Abstract
A practical method for synthesizing chiral α-amino phosphonic acid derivatives was developed. Readily available and stable N-o-nitrophenylsulfenyl (Nps) imino phosphonate was utilized as a substrate for a highly enantioselective Friedel-Crafts-type addition of indole or pyrrole nucleophiles catalyzed by chiral phosphoric acid. The resulting adduct was easily converted into N-9-fluorenylmethyloxycarbonyl (Fmoc) amino phosphonic acid, which is useful for synthesizing peptides containing an amino phosphonic acid.

Abstract
α-aminophosphonate oxadiazoles (5a-m) were prepared in high yields by reacting of 1,3,4-oxadiazole acetohydrazide (3) with appropriate aldehydes and diethyl phosphite under Kabachnik-Fields conditions using Iron triflate as a catalyst. The reaction conditions were optimized using D-optimal experimental design. Possible reaction mechanisms were considered, and structures of the new products were based upon compatible elementary and spectroscopic evidence. In vitro antitumor activities of these compounds were evaluated against human cancer cell lines of colon (HCT116), breast (MCF7) and liver (HepG2) and compared with anticancer drug, Doxorubicin, employing standard MTT assay. Compounds 5i and 5l demonstrated good antiproliferative activities against HCT116 tumor cells comparable to doxorubicin with low cytotoxicity towards normal fetal colon cell (FHC). Additionally, their capacity to activate apoptosis cascade was studied in HCT116 cell line by investigating the activation of proteolytic caspases cascade, the levels of Cytochrome C, Bax and Bcl-2. Active caspase-3 level was enhanced by 6-8-folds in HCT116 cell line when stimulated with compounds 5i and 5l compared to the control. The level of Caspases 8 & 9 was also increased signifying that intrinsic and extrinsic pathways are both activated. They also induced Bax and down regulated Bcl-2 protein level in addition to over-expressing Cytochrome C level in HCT116 cell line. Also, HCT116 cell cycle was mainly arrested at the Pre-G1 and G2/M phases when treated with compounds 5i and 5l.

Abstract
A novel class of platinum(IV) complexes comprising a monoaminophosphonate ester moiety, which can not only act as a bone-targeting group but also inhibit matrix metalloproteinases (MMPs), were designed and synthesized. Biological assay of these compounds showed that they had potent antitumor activities against the tested cancer cell lines compared with cisplatin and oxaliplatin and indicated low cytotoxicity to human normal liver cells. Particularly, the platinum(IV) complexes were very sensitive to cisplatin resistant cancer cell lines. The corresponding structure-activity relationships were studied and discussed. Related mechanism study revealed that the typical complex 11 caused cell cycle arrest at S phase and induced apoptosis in Bel-7404 cells via a mitochondrial-dependent apoptosis pathway. Moreover, complex 11 had potent ability to inhibit the tumor growth in the NCI-H460 xenograft model comparable to cisplatin.

Abstract
The mol-ecule of the title compound, C8H6ClN3O2, is built up from fused five- and six-membered rings connected to a chlorine atom and to nitro and methyl groups. The indazole system is essentially planar with the largest deviation from the mean plane being 0.007 (2) Å. No classical hydrogen bonds are observed in the structure. Two mol-ecules form a dimer organised by a symmetry centre via a close contact between a nitro-O atom and the chlorine atom [at 3.066 (2) Å this is shorter than the sum of their van der Waals radii].

Abstract
1-Benzyl-3-(substituted aryl)-5-methylfuro[3,2-c]pyrazole (YC-1) is a well-known synthetic compound with various satisfactory pharmacological activities, such as the activation of soluble guanylate cyclase (sGC) and the inhibition of hypoxia-induced factor-1α (HIF-1α). Recently, YC-1 has been demonstrated to have a potent activity on anti-fibrotic activity. However, the mechanism underlying its anti-fibrotic activity is still largely unknown. To this end, we presented here the design and synthesis of YC-1 and its novel derivatives, as well as the evaluation of their anti-fibrotic effects on activated human hepatic stellate cells (HSCs) LX-2. Moreover, the possible underlying mechanism of anti-fibrotic activity was also investigated for the first time by means of a CCK-8 assay, cell apoptosis analysis, and western blot analysis. Our study revealed that YC-1 and its derivatives suppressed activated LX-2 cell viability and induced cell apoptosis in a time- and dose-dependent manner. Western blot data demonstrated that these derivatives not only decreased the expression of α-smooth muscle actin (α-SMA), but also increased the expression of caspase-3, resulting in cell apoptosis. These findings strongly indicated that YC-1 and its derivatives, especially AC, could significantly inhibit LX-2 cell activation and induce LX-2 cell apoptosis by inhibiting α-SMA protein expression and promoting caspase-3 expression, respectively. In summary, our findings suggested that YC-1 derivatives might be potential agents for hepatic fibrosis therapy.

Abstract
The reaction of semicarbazide or thiosemicarbazide with 2-arylidene-1-tetralones under alkaline condition affords 3,3a,4,5-tetrahydro-2H-benzo[g]indazole-2-carbo(thio)amides as a mixture of cis and trans diastereoisomers of 3-H and 3a-H. The synthesis of new indazolyl-thiazol-4(5H)-ones from the condensation of cis isomer and α-halo acids is reported. A DFT study along with X-ray single crystal data of a representative compound is presented. All the eight newly synthesised indazolyl-thiazol-4(5H)-ones were screened for their antibacterial and antifungal activities and some compounds have shown promising activities.
