Multiple Splice variants of AR have been reported in the past few years. These splice variants are upregulated in most cases of CRPC resulting in poor prognosis. Most of these variants lack the ligand binding domain (LBD) but still bind to DNA resulting in constitutive activation of downstream targets. The AR-V7 splice variant has been characterized extensively and current clin. trials in CRPC are exploring the use of AR-V7 as a biomarker. New therapeutic mols. that selectively target AR-V7 are also being explored. However, there is a dearth of information available on the selectivity, phenotypic responses in AR-V7 dependent cell lines and pharmacokinetic properties of such mols. Using our proprietary computational algorithms and rational SAR optimization, we have developed a potent and selective AR-V7 degrader from a known AR DNA binding domain (DBD) binder. This mol. effectively degraded AR-V7 in a CRPC cell line and demonstrated good oral bioavailability in mouse PK studies. This tool compound can be used to evaluate the pharmacol. effects of AR-V7 degraders. Further exploration of SAR can be pursued to develop more optimized lead compounds

Geyer, Charles E. Jr. published the artcileDefinitive results of a phase III adjuvant trial comparing six cycles of FEC-100 to four cycles of AC in women with operable node-negative breast cancer: the NSABP B-36 trial (NRG Oncology), Product Details of C17H14F3N3O2S, the publication is Breast Cancer Research and Treatment (2022), 193(3), 555-564, database is CAplus and MEDLINE.

Results from adjuvant trials evaluating 6 cycles of epirubicin-based chemotherapy regimens suggested these programs may be more effective than 4 cycles of doxorubicin-based chemotherapy. NSABP B-36 was a phase III clin. trial originally designed as a 2 x 2 factorial study comparing 6 cycles of 5-FU, epirubicin, and cyclophosphamide (FEC-100) to 4 cycles of conventional doxorubicin and cyclophoshamide (AC) with celecoxib or placebo. Shortly after activation, concerns regarding increased cardiovascular risks among selective COX-2 inhibitors resulted in a decision to remove the celecoxib/placebo from the trial. Women with histol. node-neg. invasive breast cancer who had undergone primary surgery with a lumpectomy or total mastectomy were eligible. Primary endpoint was disease-free survival (DFS). Between May 2004 and July 2008, 2722 patients were enrolled. Administration of FEC-100 did not result in improvement in DFS compared to AC (HR 1.09; 95% CI 0.92-1.29, p value = 0.31). The effect of FEC-100 compared to AC on DFS was significantly different for receptor-pos. (HR 1.32, 95% CI 1.05-1.66) compared to receptor-neg. patients (HR 0.86, 95% CI 0.66-1.11) (treatment-by-receptor status interaction p value = 0.02). There was no statistically significant difference in the effect of treatment on overall survival (OS) with FEC-100 compared to AC (HR 1.06; 95% CI 0.84-1.35, p value = 0.61). Overall, Grade 3 and 4 adverse events were more frequent in the FEC-100 group. The results of B-36 do not support use of six-cycle anthracycline-based regimens in node-neg. breast cancer. Prolongation of anthracycline-based therapy with FEC-100 does not improve DFS or OS, relative to AC for 4 cycles, and was associated with expected increases in toxicity. A statistically significant interaction between treatment and hormone receptor status favoring AC in hormone-receptor-pos. breast cancers is consistent with the hypothesis that optimal duration of chemotherapy may be four cycles in these patients. Late cardiac events and deaths prior to recurrence or second cancer were infrequent on both arms, but slightly higher with FEC-100.

Ghosal, Somnath published the artcileIn silico bioinformatics analysis for identification of differentially expressed genes and therapeutic drug molecules in Glucocorticoid-resistant Multiple myeloma, Quality Control of 169590-42-5, the publication is Medical Oncology (New York, NY, United States) (2022), 39(5), 53, database is CAplus and MEDLINE.

Multiple myeloma (MM), second most common hematol. malignancy, still remains irremediable because of acquisition of drug resistance. Glucocorticoid (GC) therapy, which is used as one of the key therapies against MM, is hindered by the incidence of GC resistance. The underlying mechanism of this acquired GC resistance in MM is not fully elucidated. Therefore, the present study was aimed to identify the differentially expressed genes (DEGs), associated micro RNAs (miRNAs), and transcription factors (TFs) from the microarray datasets of GC-resistant and GC-sensitive MM cell lines, obtained from Gene Expression Omnibus (GEO) database. DEGs were identified using GEO2R tool from two datasets and common DEGs were obtained by constructing Venn diagram. Then the Gene ontol. (GO) and pathway enrichment anal. were performed using DAVID database. Genetic alterations in DEGs were examined using COSMIC database. Protein-protein interaction (PPI) network of DEGs was constructed using STRING database and Cytoscape tool. Network of interaction of DEGs and miRNAs as well as TFs were obtained and constructed using mirDIP, TRRUST, and miRNet tools. Drug gene interaction was studied to identify potential drug mols. by DGIdb tool. Six common DEGs, CDKN1A, CDKN2A, NLRP11, BTK, CD52, and RELN, were found to be significantly upregulated in GC-resistant MM and selected for further anal. miRNA anal. detected hsa-mir-34a-5p that could interact with maximum target DEGs. Two TFs, Sp1 and Sp3, were found to regulate the expression of selected DEGs. The entire study may provide a new understanding about the GC resistance in MM.

The title compounds, [Cl₂C:CC:N⁺R₂]Cl^– [I; R₂ = Me₂, (CH₂)₄, (CH₂)₂O(CH₂)₂, (CH₂)₅] react regioselectively at either the 1- or 3-position depending on the reaction pattern. Chloro substitution affording new propene iminium salts is preferred e.g. in the reaction with mercaptans, amines, and some activated arenes and hetarenes. Nucleophilic attack at the 1-position providing in allyl or allylidene structure is observed e.g. in the reaction with H₂O, EtOH, trialkyl phosphite, Me₃SiCN, Grignard reagents, and acceptor activated methylene compounds Reaction at both positions with heterocyclization to 1,3-thiazine-6-thiones occurs with thioamide functions. The regiochem. depends on a complex interplay of several factors in contrast to the FMO predicted orientation. The utility of I and some consecutive products as versatile C₃-building blocks for further syntheses is foreseeable.

Arvaniti, Olga S. published the artcileSorption of two common antihypertensive drugs onto polystyrene microplastics in water matrices, Formula: C24H29N5O3, the publication is Science of the Total Environment (2022), 155786, database is CAplus and MEDLINE.

Recent studies have shown the widespread occurrence of microplastics in multiple environmental compartments. When discharged into the aquatic environment, microplastics interact with other chems. acting as vectors of organic and inorganic micropollutants. In the present study, we examined the sorption of two commonly used antihypertensive drugs, valsartan (VAL) and losartan (LOS), onto polystyrene (PS) microplastics and we studied the effects of water matrix, solution’s pH, salinity, and microplastics’ aging on their sorption. According to the results, the sorption of VAL and LOS onto PS is a slow process that reaches equilibrium after 12 days. The sorption of both target micropollutants was pH-dependent and significantly decreased under alk. conditions. The removal of VAL was enhanced in the presence of 100 mM of Ca²⁺ while no statistical significant effects were observed when Na⁺ was added. The increase of salinity either did not affect or decreased the removal of LOS. Lower sorption of both drugs was observed when aged PS was used despite that the sp. surface area for aged PS was 39% higher than pristine. Calculation of the sorption distribution coefficient (Kd) for different water matrixes showed that the increase of matrix complexity inhibited target compounds’ removal and the sorption rate decreased from bottled water > river water ≈ treated wastewater for the two compounds For VAL, the Kd values ranged between 795 ± 63 L/kg (bottled water) and 384 ± 88 L/kg (river water), while for LOS between 4453 ± 417 L/kg (bottled water) and 3078 ± 716 L/kg (treated wastewater). Both VAL and LOS sorption onto PS microplastics can be described by hydrophobic and electrostatic interactions. The current results indicate that PS particles could affect the transportation of antihypertensive drugs in the aquatic environment causing potential adverse effects on the environment and public health.

The growing risk of antimicrobial resistance besides the continuous increase in the number of cancer patients represents a great threat to global health, which requires intensified efforts to discover new bioactive compounds to use as antimicrobial and anticancer agents. Thus, a new set of pyridothienopyrimidine derivatives 2a,b-9a,b was synthesized via cyclization reactions of 3-amino-thieno[2,3-b]pyridine-2-carboxamides 1a,b with different reagents. All new compounds were evaluated against five bacterial and five fungal strains. Many of the target compounds showed significant antimicrobial activity. In addition, the new derivatives were further subjected to cytotoxicity evaluation against HepG-2 and MCF-7 cancer cell lines. The most potent cytotoxic candidates (3a, 4a, 5a, 6b, 8b and 9b) were examined as EGFR kinase inhibitors. Mol. docking study was also performed to explore the binding modes of these derivatives at the active site of EGFR-PK. Compounds 3a, 5a and 9b displayed broad spectrum antimicrobial activity with MIC ranges of 4-16 μg/mL and potent cytotoxic activity with IC₅₀ ranges of 1.17-2.79 μM. In addition, they provided suppressing activity against EGFR with IC₅₀ ranges of 7.27-17.29 nM, higher than that of erlotinib, IC₅₀ = 27.01 nM.
