Two new indole alkaloids, 1-methylindole-7-methoxy-3-carboxaldehyde () and 7-methoxyindole-3-carboxaldehyde (), together with 7-methoxyindole-3-carboxylic acid methyl ester ( and 1-methylindole-3-carbaldehyde () were isolated from the fruiting bodies of wild Sanghuang mushroom (TL663). TLC, H-NMR and LC-MS chemical profiles of this mushroom compared with other three genera of wild Sanghuang mushroom extracts were investigated. The TLC, H-NMR and LC-MS profiles of TL663 and (SS664) were similar and significantly different from other mushrooms. These two samples indicated the same TLC chromatograms by showing prominent bands of - when observed under UV 254 nm and having sharp aldehyde proton signals of 3-carboxaldehyde indole type in H-NMR spectra. From LC-MS analyses, peaks of isolated compounds - and indole-3-carboxaldehyde () in TL663 extract and peaks of protocatechuic acid (), caffeic aldehyde (), caffeic acid () and 3,4-dihydroxybenzalacetone () phenolic acids in TL663 fraction were identified.

Revealing the impact of tadalafil-loaded proniosomal gel against dexamethasone-delayed wound healing via modulating oxido-inflammatory response and TGF-β/Macrophage activation pathway in rabbit model.

A serious challenge of the chronic administration of dexamethasone (DEX) is a delay in wound healing. Thus, this study aimed to investigate the potential of Tadalafil (TAD)-loaded proniosomal gel to accelerate the healing process of skin wounds in DEX-challenged rabbits. Skin wounds were induced in 48 rabbits of 4 groups (n = 12 per group) and skin wounds were treated by sterile saline (control), TAD-loaded proniosomal gel topically on skin wound, DEX-injected rabbits, and DEX+TAD-loaded proniosomal gel for 4 weeks.

Background: The MOVIE phase I/II trial (NCT03518606) evaluated the safety and antitumor activity of durvalumab and tremelimumab combined with metronomic oral vinorelbine in patients with advanced tumors. We present the results of the recurrent advanced cervical cancer cohort.
Methods: Patients received tremelimumab (intravenously, 75 mg, every four weeks (Q4W); four cycles max) plus durvalumab (intravenously, 1,500 mg, Q4W; 26 cycles max) and metronomic oral vinorelbine (40 mg, every three weeks (3QW)) until disease progression.
Towards Novel Antiplasmodial Agents-Design, Synthesis and Antimalarial Activity of Second-Generation β-Carboline/Chloroquine Hybrids.

As the resistance of to the existing antimalarials increases, there is a crucial need to expand the antimalarial drug pipeline. We recently identified potent antimalarial compounds, namely harmiquins, hybrids derived from the β-carboline alkaloid harmine and 4-amino-7-chloroquinoline, a key structural motif of chloroquine (CQ). To further explore the structure-activity relationship, we synthesised 13 novel hybrid compounds at the position -9 of the β-carboline ring and evaluated their efficacy in vitro against 3D7 and Dd2 strains (CQ sensitive and multi-drug resistant, respectively).

Paclitaxel is a widely used chemotherapeutic agent for the treatment of breast cancer (BC), including as a front-line treatment for triple-negative breast cancer (TNBC) patients. However, resistance to paclitaxel remains one of the major causes of death associated with treatment failure. Multiple studies have demonstrated that miRNAs play a role in paclitaxel resistance and are associated with both disease progression and metastasis.

This study aimed to summarize the clinical characteristics and prognosis of patients with bone marrow invasive follicular lymphoma (FL) and discuss the treatment modalities. This study included 183 consecutive patients with FL accompanied by bone marrow invasion and receiving regular treatment at the Hospital of Hematology, Chinese Academy of Medical Sciences, from January 2013 to December 2022. Clinical data were retrospectively collected and analyzed, and single and multifactorial analyses of survival prognosis were conducted with the Kaplan-Meier method and Cox regression model.
