On the other hand, monocycline helped quit a bit to improve depression. I was forced to discontinue it because, after a delay of about a year, I developed black and blue hyperpigmentation of the feet, ankles, and shins. It took over a year after discontinuing monocycline for the dark discolorations to disappear.

Both of them are part of a class of antibiotics called tetracyclines (tetracycline itself is actually semi-synthetic). I have tried tetracycline (itself) for acne, but as I recall it, I did not use it for long due to gastrointestinal side effects.
I did not know these drugs were anti-inflammatories. I was thinking that, as they are antibiotics, they worked by affecting the body's microbiome. I seem to be seeing an increasing number of new research studies suggesting that microbes can affect depression (and the lack thereof) in major ways, and the manipulation thereof (eg. by probiotic supplements and fecal transplants) holds promise for treating some mental disorders.
However, I'm aware that depression has been associated with inflammation. In fact, it seems to be the main successor of the old monoamine hypothesis. Therefore, more specifically (than (tetra-)cyclines) anti-inflammatory drugs may be of interest. As far as I'm aware, there are two major classes of them: corticosteriods and NSAIDs (Non-Steroidal Anti-Inflammatory Drugs). Corticosteroids can induce a condition called steroid-euphoria, and the cortisol (the endogenous corticosteroid) curve is disturbed in some types of depression (notably burnout syndrome). However, corticosteroids can be detrimental for some mental faculties (not to mention other bodily functions), such as memory.
From "Google research" for the purposes of composing this message, I found this interesting, although a bit dated, review on the effects of corticosteroids on the psyche:
https://pmj.bmj.com/content/postgradmedj/60/705/467.full.pdfTo me, it suggests that the wide variety of mental changes from steroid administration is most likely due to the upsetting or correcting of the individual balance of corticosteroid-receptor agonism. In other words, these drugs may either *cause* or *treat* certain mental conditions.
