A novel green approach for reactive printing of cotton/cellulosic regenerated blended fabrics using trisodium nitrilotriacetate.

Owing to their comfort, handle, and aesthetic characteristics, cotton fabrics will always be the first and primary choice for clothing and apparel. In recent years, regenerated cellulosic fabrics like bamboo, Tencel, and modal fabrics have had many natural advantages. Fabrics based on blending cotton fibres with regenerated cellulosic fibres are considered promising products in textile industry sectors.

Non-small cell lung cancer sensitisation to platinum chemotherapy via new thiazole-triazole hybrids acting as dual T-type CCB/MMP-9 inhibitors.

Cisplatin remains the unchallenged standard therapy for NSCLC. However, it is not completely curative due to drug resistance and oxidative stress-induced toxicity. Drug resistance is linked to overexpression of matrix metalloproteinases (MMPs) and aberrant calcium signalling.

Design, Synthesis, and Biological Evaluations of Novel Thiazolo[4,5-d]pyrimidine Corticotropin Releasing Factor (CRF) Receptor Antagonists as Potential Treatments for Stress Related Disorders and Congenital Adrenal Hyperplasia (CAH).

Corticotropin-releasing factor (CRF) is a key neuropeptide hormone that is secreted from the hypothalamus. It is the master hormone of the HPA axis, which orchestrates the physiological and behavioral responses to stress. Many disorders, including anxiety, depression, addiction relapse, and others, are related to over-activation of this system.

An ensemble multi-stream classifier for infant needs detection.

In this paper, we propose a novel multi-stream video classifier for infant needs detection. The proposed system is an ensemble-based system that combines several machine learning to improve the overall result of the state-of-the-art algorithms. It is a multi-stream in the sense that it combines the output predictions of both audio and images of infants from every single classifier employed in the system for a unified result.

Thiazolopyrimidine Scaffold as a Promising Nucleus for Developing Anticancer Drugs: A Review Conducted in Last Decade.

The thiazolopyrimidine nucleus is a bioisosteric analog of purine and an important class of N-containing heterocycles. Thiazolopyrimidine scaffolds are considered a promising class of bioactive compounds that encompass diverse biological activities, such as antibacterial, antiviral, antifungal, anticancer, corticotrophin-releasing factor antagonists, anti-inflammatory, antituberculosis, and glutamic receptors antagonists. Despite the importance of thiazolopyrimidines from a pharmacological viewpoint, there is hardly a comprehensive review on this important heterocyclic nucleus.

Design, synthesis, structural optimization, SAR, in silico prediction of physicochemical properties and pharmacological evaluation of novel & potent thiazolo[4,5-d]pyrimidine corticotropin releasing factor (CRF) receptor antagonists.

Thiazolo[4,5-d]pyrimidines as a privileged scaffold in drug discovery.

Thiazolo[4,5-d]pyrimidines are fused heterocyclic ring-systems that can be viewed at the first glance as purine isosteres. They are the 7 thia-analogs of purines via the replacement of the nitrogen at position 7 of the purine ring by a sulfur atom. Because of the structural resemblance to adenine and guanine and their related derivatives as adenosine, guanosine, cAMP, cGMP and similar biomolecules, many thiazolo[4,5-d]pyrimidines scaffold were developed and utilized by medicinal chemists to design novel therapeutics.

Three natural cembranoids from the Red Sea soft coral Sarcophyton glaucum namely (1S,2E,4R,6E,8R,11S,12R)-8,12-epoxy-2,6-cembradiene-4,11-diol, (1S,2E,4R,6E,8S,11R,12S)-8,11-epoxy-4,12-epoxy-2,6-cembradiene and (1S,4R,13S)-cembra-2E,7E,11E-trien-4,13-diol were evaluated for their inhibitory effects on mouse melanoma B16F10 cell growth. Results show that all the cembranoids strongly inhibit viability of melanoma cells particularly during 48 -72 hrs treatment and also inhibit de novo DNA synthesis and PARP activity and stimulate fragmentation of DNA. (1S,2E,4R,6E,8R,11S,12R)-8,12-epoxy-2,6-cembradiene-4,11-diol was not cytotoxic to monkey kidney CV-1 cells at the concentration that produces the anti-melanoma effects which indicates that this compound may be a good candidate for further development.

Synthesis of new thiazolo[4,5-d]pyrimidines as Corticotropin releasing factor modulators.

Corticotropin-releasing factor (CRF) is a neurohormone that plays a crucial role in integrating the body's overall response to stress.

Compound (3) produced cytotoxic effects at the same concentration range it produces its antitumor effects.

Synthesis of substituted pyrimidines as corticotropin releasing factor (CRF) receptor ligands.

Corticotropin releasing factor (CRF) is a neuropeptide hormone produced from the hypothalamus that controls the secretion of corticotropin (ACTH) from the anterior pituitary gland that, in turn, prompts the adrenal glands to secrete glucocorticoids. This involvement in the hypothalamic-pituitary-adrenal axis (HPA) in response to stress and also playing a key role in behavioral, cardiovascular, immune and gastrointestinal systems made CRF binding to its receptors an important target in drug discovery aiming to develop lead compounds with the potential to treat various stress-related disorders including depression, anxiety and addictive disorders. Several non-peptide CRF1 receptor antagonists were developed by pharmaceutical companies and are currently in clinical trials with the aim of improving the health consequences of chronic stress and for use in the clinical management of anxiety and stress.

Chemopreventive effect of sarcophine-diol on NOR-1-induced TPA-promoted skin carcinogenesis in female HOS:HR-1 mice.

The cancer chemopreventive potential of sarcophine-diol in a chemical carcinogen initiation-promotion experimental tumor model in mice was evaluated. Sarcophine-diol, when given orally, afforded significant protection in the mouse skin cancer model initiated by the topical administration of (+/-)-(E)-4-methyl-2-[(E)-hydroxyamino]-5-nitro-6-methoxy-3-hexanamide (NOR-1) and promoted by 12-O-tetradecanoylphorbol-13-acetate (TPA). These findings, along with our initial reports, suggest that sarcophine-diol is an effective cancer chemopreventive agent, even when administered orally and at a very low dose and thus indicating possible potential human applications in the control of malignancy.

Sarcophine-diol inhibits expression of COX-2, inhibits activity of cPLA2, enhances degradation of PLA2 and PLC(γ)1 and inhibits cell membrane permeability in mouse melanoma B16F10 cells.

Sarcophine-diol (SD) is a semi-synthetic derivative of sarcophine with a significant chemopreventive effect against non-melanoma skin cancer both in vitro and in vivo. Recently, we have studied the effect of SD on melanoma development using the mouse melanoma B₁₆F₁₀ cell line. In this study, our findings show that SD suppresses cell multiplication and diminishes membrane permeability for ethidium bromide (EB), a model marker used to measure cell permeability for Ca²⁺ ions.
