The CPB2-AS1 gene, or "carboxypeptidase B2 (serum) antisense RNA 1," is a long non-coding RNA (lncRNA) involved in various biological processes and has been implicated in several diseases. This gene is located on chromosome 16 in humans.

### 1. Associated Genes
While comprehensive databases like NCBI and UniProt might not list them, additional research identifies the following genes that may be functionally or regulatory related to CPB2-AS1:
- **CPB2**: The protein-coding gene for carboxypeptidase B2, an enzyme that plays a role in coagulation and inflammation.
- **VEGF**: Vascular endothelial growth factor genes, which may be influenced by the regulatory networks involving lncRNAs like CPB2-AS1.
- **IL-6**: Interleukin 6, which is involved in immune responses and inflammatory processes and can be affected by lncRNA expression.

### 2. Aging or Age-Related Diseases
The roles of lncRNAs, including CPB2-AS1, in aging and age-related diseases are an area of active research. Evidence links dysregulation of lncRNAs to various age-related diseases, including:
- **Cardiovascular Diseases**: Due to its involvement in inflammation and coagulation pathways, alterations in CPB2-AS1 expression may be relevant to cardiovascular aging and related disease mechanisms.
- **Cancer**: Some studies suggest that lncRNAs may affect cancer pathways, and aberrant expression of CPB2-AS1 has been tied to cancer phenomena, potentially through modulation of tumor microenvironments and response to treatment.

### 3. Drug Interactions
As of now, specific drugs or drug classes that directly interact with CPB2-AS1 are not well-defined in the literature. Some drugs affecting the pathways related to its associated gene products (like anticoagulants or drugs affecting inflammatory responses) may indirectly influence the expression or activity of CPB2-AS1.

### 4. Pathways and Biological Processes
CPB2-AS1 is involved in various biological processes and may influence:
- **Regulation of Gene Expression**: As an lncRNA, it can modulate the expression of nearby genes or distant targets through epigenetic modifications or transcriptional regulation.
- **Inflammation Pathways**: Given its association with inflammation-related genes and processes, it may play a role in the inflammatory response.
- **Coagulation Cascade**: By being an antisense RNA to CPB2, it could be directly involved in modulation of blood coagulation factors.
- **Cancer Biology**: Involvement in pathways relevant to proliferation, apoptosis, or metastasis may also be inferred based on the role of similar lncRNAs.

Continued investigation into the functional roles and interactions of CPB2-AS1 is essential for fully elucidating its contributions to health and disease, especially in the context of aging and associated pathologies.
