In the present study, a quantitative structure-activity relationship study (QSAR) investigation was conducted on a data set of 31 novel indolinyl thiazole-based inhibitors of SR-BI mediated lipid uptake. Method:: To build the QSAR model, Multiple linear regression analysis (MLR), partial least square analysis (PLS), and neural analysis (NN) were performed which were further evaluated internally as well as externally for the prediction of activity. The best QSAR model for MLR was selected with a correlation coefficient (r2) of 0.937, cross-validation r2cv of 0.908, and a standard error (S) value of 0.253. For PLS, r2 was 0.937 and for FFNN r2 was 0.961 (for the training set). This was further evaluated externally by a test set having r2 values 0.870 (MLR), 0.863(PLS), and 0.933(neural network) analysis. Result:: The final model comprised hydrophobic parameters (Lipole Z component) and steric parameters (molar refractivity and K alpha2 index). Conclusion:: All these descriptors generated comparable results which prove that the model generated is sound and has good predictability.","PeriodicalId":18059,"journal":{"name":"Letters in Drug Design & Discovery","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140575796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: This study aimed to synthesize new indazole derivatives and evaluate their antiproliferative activity to produce new anti-cancer agents. Method: The 2-aryllidenecyclohexane-1,3-dione derivatives 3a-c were obtained through the reaction of cyclohexane-1,3-dione with aromatic aldehydes used for the synthesis of thieno-[3,2-e]indazole derivatives. These derivatives were characterized by extensive analytical and spectral studies and were further used as starting materials for some heterocyclic transformations to produce biologically active compounds. The antiproliferative activities of the newly synthesized compounds were evaluated against the six cancer cell lines, A549, HT-29, MKN-45, U87MG, SMMC-7721, and H460. Most of the tested compounds exhibited high cytotoxicity except a few compounds. Results: In this study, new compounds were synthesized, characterized, and evaluated toward the selected six cancer cell lines. All tested compounds displayed potent c-Met enzymatic activity with IC50 values ranging from 0.25 to 10.30 nM and potent prostate PC-3 cell line inhibition with IC50 values ranging from 0.17 to 9.31mM.

Due to the structural identity with cGMP; PDE5 inhibitors competitively bind with PDE5 and limit cGMP hydrolysis, which raises the cGMP level in smooth muscle cells and lengthens the duration of an erection. PDE5 inhibitors were also found to be beneficial for coronary vasculopathy, pulmonary arterial hypertension, and benign prostatic hyperplasia.

The indole scaffold in this category is widely distributed in nature and present in many active compounds, especially anti-cancer agents. Due to its unique physicochemical and biological properties, the indole platform has been considered a favorable scaffold in anti-cancer drug design and development. Various indole compounds (synthetic, semisynthetic, and natural) show remarkable anti-proliferative activity. According to the recent literature, this review describes the role of indole scaffolds as anti-cancer agents. Indole was reported to induce anti-tumor activity through multiple mechanisms, for example, Epidermal Growth Factor Receptors (EGFR), histone deacetylase (HDAC), kinase, DNA-topoisomerases, and tubulin inhibition. The current review focuses on some indole compounds with amazing effects against different types of cancers as there are too many FDA-approved drugs, for example, osimertinib, alectinib, and anlotinib in NSCLC treatment, panobinostat in multiple myeloma, midostaurin in acute myeloid leukemia treatment, etc. Moreover, several compounds are still in clinical trials to treat different cancer types. Additionally, there are some oxindole derivatives with potent inhibition against different types of tumors, such as ovarian cancer, colorectal cancer, and prostate cancer. Different series of oxindoles are promising and recommended for further studies due to their remarkable inhibition of tumor cells. Accordingly, the collection of data on a pharmacologically significant motif might aid researchers in further employing indoles in developing novel anti-cancer drugs with potentially fewer side effects and higher potency against this rapidly spreading disease.","PeriodicalId":18059,"journal":{"name":"Letters in Drug Design & Discovery","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140106955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

P-glycoprotein (P-gp), a highly expressed protein in the BBB, plays a fundamental role in transporting Aβ from the brain to the blood and protecting the blood-brain barrier (BBB). The dysfunction or decreased abundance of this transporting protein is associated with the accumulation of Aβ, leading to dementia and cognitive deficits. In this review article, we consolidate the existing literature on the impact of P-gp in the pathophysiology and therapy of AD. Current evidence claims that p-gp is involved in AD pathology and that enhancing the activity of this transporter may be a promising therapeutic approach to hinder AD progression. There is also a growing interest in P-gp as a potential therapeutic target for AD. Hence, ongoing clinical trials and research should investigate P-gp inhibitor efficacy as a therapeutic approach for improving AD drug delivery to the brain and treatment outcomes.","PeriodicalId":18059,"journal":{"name":"Letters in Drug Design & Discovery","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140018047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
