5-HT2A Receptor Ligands Against Depression
According to the World Health Organization, depression is a multifactorial disorder that affects around 350 million people worldwide. The most widespread monoamine of the CNS-serotonin (5-HT) is believed to play a vital role in the pathomechanism of this condition, and the importance of the neurotransmitter is elevated by the "serotonin hypothesis", linking the presence of the depression-like symptoms with diminished 5-HT concentration in certain brain regions. Serotonin acts its biological effects via numerous receptors. Out of all seven types of serotonin receptors, the serotonin 2A receptor has been identified as a most promising molecular target valuable for the treatment of mood disorders. Recent medicinal chemistry findings on the structure and function of the serotonin 2A (5-HT2A) receptor facilitated design and discovery of novel anti-depressants.

5-Hydroxytryptamine 2B Receptor
Since the first characterization of the 5-hydroxytryptamine 2B receptor (5-HT2BR) in 1992, significant progress has been made in understanding the biological function, the structure, and small-molecule pharmaceutical ligands of the 5-HT2BR. Emerging evidence has suggested that the 5-HT2BR is implicated in the regulation of the cardiovascular system, fibrosis disorders, cancer, gastrointestinal (GI) tract, and nervous system. Eight crystal complex structures of the 5-HT2BR bound with different ligands provided great insights into ligand recognition, activation mechanism, and biased signaling. Numerous 5-HT2BR antagonists have been discovered and developed, and several of them have been advanced to clinical trials. It is expected that the novel 5-HT2BR antagonists with high potency and selectivity will lead to first-in-class drugs in various therapeutic areas.

7-Methyljuglone in Tuberculosis Treatment
7-Methyljuglone (7-MJ) is a pure compound isolated from the roots of Euclea natalensis A. DC., a shrub indigenous to South Africa. It exhibits significant promise as a potential treatment for the highly communicable disease tuberculosis (TB), owing to its effective antimycobacterial activity against Mycobacterium tuberculosis.

89Zr-PET Imaging Other than Immuno-PET
89Zr is an emerging radionuclide that plays an essential role in immuno‐positron emission tomography (PET) imaging. Immuno‐PET combines the sensitivity of PET with the specificity of antibodies, and thus is useful for predicting the efficacy of radioimmunotherapy and antibody therapies, imaging target expression, detecting target‐expressing tumors, and the monitoring of anti‐cancer chemotherapies. PET using 89Zr is not confined to antibody imaging. In this review, we discuss 89Zr‐PET applications other than immuno‐PET.

A Breakthrough Brought about by Targeting KRASG12C
KRAS is the most frequently mutated member of the RAS family, present in 96% of pancreatic ductal adenocarcinoma (PDAC), 52% of colorectal, 32% of lung carcinomas, and to a lesser extent in a variety of other cancers, with alterations mostly occurring at codon G12, G13, and Q61.

A Brief Clinical Overview of Retinitis Pigmentosa
Retinitis pigmentosa (RP) is a hereditary disease that causes the degeneration of photoreceptor cells in the retina, starting with the rods, leading to a gradual loss of vision over time. RP is the most common type of inherited retinal dystrophy and affects over 1.5 million people worldwide, leading to a high burden on patients and society. Common symptoms of RP include nyctalopia and gradual loss of peripheral vision, which can ultimately lead to blindness. RP is one of the primary causes of visual disability and blindness in individuals under 60 years old.

A Defective Viral Particle Approach to COVID-19
Defective interfering particles, which arise naturally and interfere with viruses, have long inspired the idea that they might be adapted to treat viral diseases. Here, we explore how such defective interfering particles and other therapeutic nanoparticles might be designed and constructed to interfere with SARS-CoV-2.

A Disintegrin and Metalloproteinase (ADAM) Family
A disintegrin and metalloproteinase (ADAM) proteins are proteolytic enzymes that are responsible for destroying the extracellular matrix, but they also have adhesive properties. Recent investigations have demonstrated that the expression of several ADAMs is upregulated in gastrointestinal (GI) tumour cells and have linked the secretion of these proteins to pathogenesis of GI malignancies.
