Epigenetic compounds targeting pharmacological target lysine specific demethylase 1 and its impact on immunotherapy, chemotherapy and radiotherapy for treatment of tumor recurrence and resistance. Biomed Pharmacother 2023; 157:113934. [PMID: 36395607 DOI: 10.1016/j.biopha.2022.113934] [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: 09/17/2022] [Revised: 10/22/2022] [Accepted: 10/26/2022] [Indexed: 11/15/2022] Open
Abstract
It has been proven that metastatic recurrence and therapeutic resistance are linked. Due to the variability of individuals and tumors, as well as the tumor's versatility in avoiding therapies, therapy resistance is more difficult to treat. Therapy resistance has significantly restricted the clinical feasibility and efficacy of tumor therapy, despite the discovery of novel compounds and therapy combinations with increasing efficacy. In several tumors, lysine specific demethylase 1 (LSD1) has been associated to metastatic recurrence and therapeutic resistance. For researchers to better comprehend how LSD1-mediated tumor therapy resistance occurs and how to overcome it in various tumors, this study focused on the role of LSD1 in tumor recurrence and therapeutic resistance. The importance of therapeutically targeted LSD1 was also discussed. Most gene pathway signatures are related to LSD1 inhibitor sensitivity. However, some gene pathway signatures, especially in AML, negatively correlate with LSD1 inhibitor sensitivity, but targeting LSD1 makes the therapy-resistant tumor sensitive to physiological doses of conventional therapy. We propose that combining LSD1 inhibitor with traditional tumor therapy can help patients attain a complete response and prevent cancer relapse.

Ultrasonic-Assisted Synthesis of Benzofuran Appended Oxadiazole Molecules as Tyrosinase Inhibitors: Mechanistic Approach through Enzyme Inhibition, Molecular Docking, Chemoinformatics, ADMET and Drug-Likeness Studies. Int J Mol Sci 2022; 23:ijms231810979.

Abstract
Furan-oxadiazole structural hybrids belong to the most promising and biologically active classes of oxygen and nitrogen containing five member heterocycles which have expanded therapeutic scope and potential in the fields of pharmacology, medicinal chemistry and pharmaceutics. A novel series 5a-j of benzofuran-oxadiazole molecules incorporating S-alkylated amide linkage have been synthesized using ultrasonic irradiation and screened for bacterial tyrosinase inhibition activity. Most of the synthesized furan-oxadiazole structural motifs exhibited significant tyrosinase inhibition activity in the micromolar range, with one of the derivatives being more potent than the standard drug ascorbic acid. Among the tested compounds, the scaffold 5a displayed more tyrosinase inhibition efficacy IC50 (11 ± 0.25 μM) than the ascorbic acid IC50 (11.5 ± 0.1 μM). Compounds 5b, 5c and 5d efficiently inhibited bacterial tyrosinase with IC50 values in the range of 12.4 ± 0.0-15.5 ± 0.0 μM. The 2-fluorophenylacetamide containing furan-oxadiazole compound 5a may be considered as a potential lead for tyrosinase inhibition with lesser side effects as a skin whitening and malignant melanoma anticancer agent.

Abstract
Pyrazolines are five-membered heterocycles possessing two adjacent nitrogens. They have attracted significant attention from organic and medicinal chemists due to their potent biological activities and the numerous possibilities for structural diversification. In the last decade, they have been intensively studied as targets for potential anticancer therapeutics, producing a steady yearly rise in the number of published research articles. Many pyrazoline derivatives have shown remarkable cytotoxic activities in the form of heterocyclic or non-heterocyclic based hybrids, such as with coumarins, triazoles, and steroids. The enormous amount of related literature in the last 5 years prompted us to collect all these published data from screening against cancer cell lines, or protein targets like EGFR and structure activity relationship studies. Therefore, in the present review, a comprehensive account of the compounds containing the pyrazoline nucleus will be provided. The chemical groups and the structural modifications responsible for the activity will be highlighted. Moreover, emphasis will be given on recent examples from the literature and on the work of research groups that have played a key role in the development of this field.

Abstract
A novel synthetic route toward vilazodone is described by using 4-cyanoaniline and 5-bromo-2-hydroxybenzaldehyde as starting materials, with an overall yield of 24% and 99% purity. First, the intermediate (3-(4-chlorobutyl)-1 H-indole-5-carbonitrile) is synthesized via diazotization of 4-cyanoaniline, followed by Fischer indole cyclization with 6-chlorohexanal. Subsequently, another intermediate, 5-(piperazin-1-yl)benzofuran-2-carboxamide, is generated via aromatic nucleophilic substitution of 5-bromobenzofuran-2-carboxamide with piperazine. Finally, vilazodone is obtained via nucleophilic substitution of the above two key intermediates by treatment with Et3N/K2CO3. In comparison to the original process, this route avoids the use of expensive and toxic reagents and resolves issues such as safety, environmental concerns, and high costs.

Abstract
New benzofuranhydrazones 3-12 were easily prepared and assayed for their radical-scavenging ability. Hydrazones 3-12 showed different extent antioxidant activity in DPPH, FRAP and ORAC assays. Good antioxidant activity is related to the number and position of hydroxyl groups on the arylidene moiety. High antioxidant activity is showed by the 2-hydroxy-4-(diethylamino)benzylidene derivative 11. Furthermore, hydrazones 3-12 showed photoprotective capacities with satisfactory in vitro SPF as compared to the commercial PBSA sunscreen filter. The antiproliferative effects of the hydrazones 3-12 was tested on erythroleukemia K562 and Colo-38 melanoma human cells. All the compounds showed growth inhibition in the micromolar to sub micromolar concentration range. If taken together these results points to benzofuran hydrazones as potential multifunctional molecules especially in the treatment of neoplastic diseases being the good antioxidant properties of 5, 7 and 11 correlated to their high antiproliferative activity.

Abstract
Aim: Simultaneous inhibition of 5-LOX/COX may enhance anti-inflammatory effects and reduce side effects. Hence, synthesis of novel dual inhibitors of 5-LOX/COX is an important strategy for treatment of inflammation. Results/methodology: The target compounds were designed to hybridize benzothiophene scaffold or its bioisostere benzofuran with various anti-inflammatory pharmacophore hetercycles through different atoms spacers. Compounds 4a, 4c, 4d, 5b, 7a, showed significant in vitro LOX inhibitory activity higher than that of meclofenamate sodium. Compounds 4b, 4e, 4f, 5a exhibited significant in vitro COX-2 inhibition higher than celecoxib and in vitro LOX inhibitory activity twice that of reference. These compounds elicited significant in vivo anti-inflammatory activities higher than celecoxib in formalin-induced paw edema test. Compound 4e exhibited gastrointestinal safety profile as celecoxib. The results were also consistent with the docking studies. Conclusion: Compound 4e could be considered as structural lead for the development of a new class of anti-inflammatory agents with better safety profile.

Abstract
p53-independent malignant cancer is still severe health problem of human beings. HIF-1 pathway is believed to play an important role in the survival and developing progress of such cancers. In the present study, with the aim to inhibit the proliferation of p53-independent malignant cells, we disclose the optimization of 6a, the starting compound which is discovered in the screening of in-house compound collection. The structure-activity relationship (SAR) is summarized. The most potent derivative 8d, inhibits the proliferation of both p53-null and p53-mutated cells through inhibition of HIF-1 pathway. Our findings here provide a new chemotype in designing potent anticancer agent especially against those p53-independent malignant tumors.

Abstract
INTRODUCTION Chemotherapy is the current standard treatment for hematological malignancies for both curative and palliative purposes. Unfortunately, in the current treatment scenario chemotherapy resistance is an issue that is know to lead to a relapse in cancer. The multidrug resistance 1 (MDR1) gene is often involved in drug resistance and, so far, the best studied mechanism of resistance relates to the level of P-glycoprotein (P-gp) expression on cancer cells; however, correlation with single nucleotide polymorphism (SNP) in the MDR1 gene has also been observed via a number of different mechanisms that interfere with function and expression of P-gp. AREAS COVERED This article describes the influence of P-gp expression and SNP on the MDR1 gene in non-Hodgkin's lymphoma (NHL) and their effect on both its risk and outcome. The authors also provide a brief summary of the more important therapeutic options, which aim to overcome this drug resistance mechanism, and discuss their known mechanisms of action. EXPERT OPINION There is evidence pertaining to an association between the outcome of NHL and P-gp expression. However, the authors emphasize the need for more studies to reinforce this evidence. Furthermore, there is a definite need for the therapeutic targets, which provide tumor cellular lines of interest, to be tested in humans, in order to better evaluate their toxicity and overall effect on the outcome. The ultimate aim of this research is to develop specifically designed therapies that are tailored to the intrinsic characteristics of specific patients.

Abstract
A novel series of 4-methoxy, and 4,9-dimethoxy-5-substituted furo[2,3-g]-1,2,3-benzoxathiazine-7,7-dioxide derivatives 3a,b, 10a–g and 11a–g were prepared in good yields via the reaction of 4-methoxy (1a) and 4,7-dimethoxy-5-acetyl-6-hydroxybenzofurans (1b) and their α,β-unsaturated keto derivatives 6a–g and 7a–g with chlorosulfonyl isocyanate (CSI). On the other hand, N-chlorosulfonyl carbamate derivatives 4a,b, 12a,b and 13a,b were prepared and allowed to react with piperidine to give the corresponding N-piperidinosulfonyl carbamate derivatives 5a,b, 14a,b and 15a,b, respectively. Sixteen new target compounds 3a,b, 10a–g, and 11a–g were tested for their DPPH radical-scavenging, and in vitro antiproliferative activity against A-549, MCF7 and HCT-116 cancer cell lines. Compounds 10a, 11c, 11e, and 11g showed moderate DPPH radical-scavenging activity compared to ascorbic acid at 100 μg/mL. 4,9-Dimethoxy-5-substituted styrylfuro[3,2-g]-1,2,3-benzoxathiazine-7,7-dioxides 11a, 11b, and 11c were found to be highly active against A-549 and HCT-116 cancer cell lines with IC50 values ranging from 0.02 to 0.08 μmol/mL compared to doxorubicin with IC50 = 0.04 and 0.06 μmol/mL, respectively.

Abstract
A series of 2-pyrazolines 5-9 have been synthesized from α,β-unsaturated ketones 2-4. New 2-pyrazoline derivatives 13-15 bearing benzenesulfonamide moieties were then synthesized by condensing the appropriate chalcones 2-4 with 4-hydrazinyl benzenesulfonamide hydrochloride. Ethyl [1,2,4] triazolo[3,4-c][1,2,4]triazino[5,6-b]-5H-indole-5-ethanoate (26) and 1-(5H-[1,2,4]triazino[5,6-b] indol-3-yl)-3-methyl-1H-pyrazol-5(4H)-one (32) were synthesized from 3-hydrazinyl-5H-[1,2,4]triazino[5,6-b]indole (24). On the other hand ethyl[1,2,4]triazolo[3,4-c][1,2,4]triazino[5,6-b]-5,10-dihydroquinoxaline- 5-ethanoate (27) and 1-(5,10-dihydro-[1,2,4]triazino[5,6-b]quinoxalin-3-yl)-3-methyl-1H-pyrazol-5(4H)-one (33) were synthesized from 3-hydrazinyl-5,10-dihydro-[1,2,4]triazino[5,6-b]quinoxaline (25) by reaction with diethyl malonate or ethyl acetoacetate, respectively. Condensation of 6,6-dimethyl-4-oxo-4,5,6,7-tetrahydro-1H-indole-2-carbaldehyde (1') with compound 24 or 25 afforded the corresponding Schiff's bases 36 and 37, respectively. Reaction of the Schiff's base 37 with benzoyl hydrazine or acetic anhydride afforded benzohydrazide derivative 39 and the cyclized compound 40, respectively. Furthermore, the pyrazole derivatives 42-44 were synthesized by cyclization of hydrazine derivative 25 with the prepared chalcones 2-4. All the newly synthesized compounds have been characterized on the basis of IR and 1H-NMR spectral data as well as physical data. Antimicrobial activity against the organisms E. coli ATCC8739 and P. aeruginosa ATCC 9027 as examples of Gram-negative bacteria, S. aureus ATCC 6583P as an example of Gram-positive bacteria and C. albicans ATCC 2091 as an example of a yeast-like fungus have been studied using the Nutrient Agar (NA) and Sabouraud Dextrose Agar (SDA) diffusion methods. The best performance was found for the compounds 16, 17, 19 and 20.

Abstract
A facile synthesis of hitherto unreported 3-(2-benzofuroyl)carbazoles 3a-k, 3,6-bis(2-benzofuroyl)carbazoles 5a-k, and naphtho[2,1-b]furoylcarbazoles 3l and 5l is described. The synthesis mainly relies on the ultrasound-assisted Rap-Stoermer reaction of 3-chloroacetyl- (1) or 3,6-dichloroacetyl-9-ethyl-9H-carbazole (4) with various salicylaldehydes 2a-k as well as 2-hydroxy-1-naphthaldehyde (2l) in CH(3)CN with the presence of PEG-400 as catalyst. The procedure offers easy access to benzofuroylcarbazoles in short reaction times and the products are obtained in moderate to good yields.
