Asymmetric Synthesis of the -Vinigrol Tricyclic Core Enabled by a Wolff Rearrangement Strategy and Formal Total Synthesis of (-)-Vinigrol.

A new approach to construct the tricyclic framework of the diterpenoid vinigrol is described. The challenging 1,5-butanodecahydronaphthalene core was established efficiently and diastereoselectively through a combination of type II [5 + 2] cycloaddition and Wolff rearrangement. In addition, a formal total synthesis of (-)-vinigrol was achieved in 12 steps, in which Baran's intermediate was efficiently produced from a known compound by a two-step sequence involving a stereoselective α-hydroxylation and a diastereoselective α-ketol rearrangement.

Synthesis of Spirotricyclic Core of Bonnadiene.

We herein describe a new approach for the efficient synthesis of the tricyclic core of diterpene bonnadiene. The synthetically challenging and unusual [6-7-5] spirotricyclic skeleton including the all-carbon quaternary stereocenter, was installed diastereoselectively via a type II [5 + 2] cycloaddition, followed by a unique vinylogous semipinacol rearrangement. The described chemistry demonstrates the feasibility of making the [6-7-5] spirotricyclic skeleton of the final product from the strained bridged [7-8-5] ring system.

Novel combination strategy of high intensity focused ultrasound (HIFU) and checkpoint blockade boosted by bioinspired and oxygen-supplied nanoprobe for multimodal imaging-guided cancer therapy.

Background: High-intensity focused ultrasound (HIFU) has shown considerable promise in treating solid tumors, but its ultrasonic energy is easily attenuated, resulting in insufficient energy accumulation in the target area. Moreover, HIFU ablation alone may inevitably lead to the presence of residual tumors, which may cause tumor recurrence and metastasis. Here, we describe a synergistic regimen combining HIFU facilitation with immunomodulation based on a novel oxygen-carrying biomimetic perfluorocarbon nanoparticle (M@P-SOP) to stimulate immunogenic cell death in tumor cells while alleviating immune suppression tumor microenvironment.

Biomimetic, pH-Responsive Nanoplatforms for Cancer Multimodal Imaging and Photothermal Immunotherapy.

Photothermal therapy (PTT), by converting light to thermal energy, has become a novel and noninvasive technique for tumor thermal ablation in clinical practice. However, as a result of phagocytosis of reticuloendothelial cells, current photothermal agents (PTAs) derived from exogenous materials suffer from incompetent tumor targeting and brief internal circulation time. The resulting poor accumulation of PTAs in the target area severely reduces the efficacy of PTT.

Loss of function of CMPK2 causes mitochondria deficiency and brain calcification.

Brain calcification is a critical aging-associated pathology and can cause multifaceted neurological symptoms. Cerebral phosphate homeostasis dysregulation, blood-brain barrier defects, and immune dysregulation have been implicated as major pathological processes in familial brain calcification (FBC). Here, we analyzed two brain calcification families and identified calcification co-segregated biallelic variants in the CMPK2 gene that disrupt mitochondrial functions.
